+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          59 Temple Place - Suite 330, Boston, MA
+                          02111-1307, USA.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Release notes for Eterm Development Release 0.8
+-----------------------------------------------
+
+Software Requirements
+---------------------
+- The usual X11R6 stuff
+- Rasterman's Imlib and the libraries it needs. Visit
+  http://www.labs.redhat.com/imlib/ for more information.
+- Even though Eterm works with any window manager, you just might get extra
+  fancies by using the Enlightenment window manager from Rasterman and
+  Mandrake - http://www.enlightenment.org/ for more information. Now go see
+  what your desktop can look like with E. :) -vendu
+
+Documentation to read
+---------------------
+- The FAQ at http://www.eterm.org/
+- Run "Eterm -h" - you'll see the command line options.
+
+ATTENTION!  Active Tags Warning!
+--------------------------------
+
+NOTE: It looks like the latest resize-crashes happen in the active tags
+code. We'll try to get this fixed as soon as possible. Until then, if you
+want to use tags, you may want to see the FIXME notes in screen.c for what
+NULL pointer checks to remove.
+
+Preliminary support for active tags by Nat Friedman has been added.
+Thanks, Nat :) (http://dingus.mit.edu/ for more info)
+
+This will definitely need more work :) Sorry if it's buggy (I'd expect it
+to be >:). -vendu
+
+Building Eterm 0.8
+------------------
+
+From the toplevel Eterm source tree directory:
+    ./configure
+    make
+	
+With better optimization flags
+
+ - For gcc 2.7.2.1 and older:  make "CFLAGS=-O2 -fno-strength-reduce"
+ - For Intel-based platforms with new gcc compilers:  make "CFLAGS=-O2 -m486"
+ - For Intel-based platforms with new gcc compilers, more optimization:
+     make "CFLAGS=-O3 -m486 -malign-loops=2 -malign-jumps=2 -malign-functions=2"
+ - For Pentium machines with egcs or pgcc:
+     make "CFLAGS=-O6 -mpentium -malign-loops=2 -malign-jumps=2 -malign-functions=2"
+       - Eterm seems to compile OK with pgcc 1.0.1. DEFINITELY use the -malign
+         flags, they seem to speed things up quite considerably for Pentium
+         processors :)
+	
+Installing Eterm
+----------------
+
+After performing the build step above, run:
+    make install
+
+Standard Disclaimer
+-------------------
+
+The authors don't take any responsibility for any damage this program
+may do. We are doing this in our spare time. If you don't like this
+program, don't use it.
+
+Eterm is based on rxvt 2.21. This development release of Eterm
+has been hacked together by Tuomo Venalainen (vendu@cc.hut.fi)
+and Michael Jennings (mej@tcserv.com). Thanks to Rasterman
+(aka Carsten Haitzler) and Michael Kellen, as well as to all the
+other people who have provided patches.  Thanks to all regulars 
+from the #E IRC channel for helping us test Eterm.
+
+The development of Eterm will be continued. The sources need to be
+converted into human-readable format ;-). More features will be added
+as well. We'll continue cleaning up and patching the sources to make
+Eterm more robust, secure and portable.
+
+NOTE: Support for libXpm was dropped off in DR 0.3. Imlib does a much
+      better job at loading and scaling the background pixmaps. And hey,
+      it's Eterm, ya know :-)
+
+Future Plans
+------------
+
+There will be minimal further development on this incarnation of Eterm.
+We have begun Project Resurrection, which is a complete rewrite of Eterm
+with a completely different philosophy of design.  Please visit
+http://ganja.tky.hut.fi/Resurrection/ for more information.
+
+Notes
+-----
+
+- In case you need utmp support, you'll have to run Eterm "setuid root"
+  As root, do: "chmod 4755 Eterm" Make SURE the Eterm binary is owned by
+  user=root, group=root (on BSD, i think it should be group=wheel):
+
+	1. chown root.root Eterm
+	2. (BSD) chown root.wheel Eterm
+
+  Note that in this version, utmp support will be turned on automagically
+  only on Linux and FreeBSD. If you want to try it on other platforms,
+  add -DUTMP_SUPPORT to your compilation flags. An example:
+    make "CFLAGS=-O -DUTMP_SUPPORT"
+
+- The only fonts I know that will display ANSI art correctly are Raster's
+  nexus and vga;
+- If you want to use colorful ANSI prompts (at least bash can show them),
+  make sure to make them end with a new line character ('\n')>
+
+Development Notes
+-----------------
+
+- ATTENTION! Ignore warnings like this:
+  options.c:1454: warning: unsigned int format, long unsigned int arg (arg 3)
+  - type casting or otherwise screwing around can break text colors bad :)
+- The sources don't compile with the GCC profiling flag (-gp) yet;
+
+Troubleshooting
+---------------
+
+- See feature.h;
+- In case you have problems, try commenting out #define NDEBUG in feature.h:
+  /* #define NDEBUG */
+
+E-n-Joy! ;-)   -- vendu & mej

+Release Notes
+=============
+
+This document includes a summary of major changes for each revision of Eterm.
+
+Changes made to rxvt 2.21 include
+---------------------------------
+
+- Better (read: working) implementation of utmp logging and added security;
+  needs to be tested on different platforms;
+- Support for Rasterman's Imlib - used for loading and scaling the background
+  pixmaps;
+- The command line option -pixmap now takes '@' as the delimiter between
+  the pixmap name and geometry. The old delimiter, ';', is NOT supported
+  any more. It was UGLY. Period. <g> ;
+- A new command line option, --scale or -@, was added. It will scale the background
+  pixmap "to fit"; to fill the whole background of the Eterm window;
+- The binary was renamed to Eterm;
+- Several bug/annoyance fixes. For example, fixed a problem with DEBUG_UTMP
+  that printed garbage when running with the debugging messages enabled.
+  See also #define NDEBUG in feature.h;
+- Minor speedups.
+
+More changes for 0.3 (included in some 0.2 versions), as described by Michael:
+
+ - Installs signal handlers that, among other things, make core
+   dumps secure by revoking privs and changing its umask to 077.
+   It also prompts for whether or not it should dump core, timing
+   out after 10 seconds or if it gets a SIGT(STP|TIN|TOU)
+ - Changes stuff that said rxvt to Eterm (most places, but I probably
+   missed a few).
+ - Fixes SVR4/utmpx compile under HP-UX 10.X
+
+Utmp logging support was fixed to work on FreeBSD (tested on 2.1.5 and 2.2.2)
+for 0.3a. Thanks to Brian Gottlieb for doing it.
+
+Changes made to 0.3b include a few portability additions and fixes (HP-UX,
+OSF/1) and a few changed (commented out) #define's in feature.h.
+
+Eterm DR-0.4x included a number of patches for bold fonts, security,
+utmp logging, etc.
+
+Several bugs were fixed for DR 0.5.  Thanks to Michael Kellen for his
+Solaris patch.
+
+Thanks go to Steve <steve@rage.org> for his help with security.
+
+Changes in DR-0.6:
+------------------
+
+ - Finally got the distribution tree cleaned up to remove most all traces
+   of left-over rxvt SPAM(tm).  For now, however, credit for most of the
+   docs still remains with the rxvt people.
+ - No more .Xdefaults support.  The X Resource Manager (Xrm) code has
+   several known security holes which make any program making
+   XGetDefault() calls insecure.  Since Eterm generally runs as root,
+   this is unacceptable.  So too is reading .Xdefaults directly, which
+   it had been doing up until now.  From DR-0.6 on, it will read (in
+   proper Enlightened fashion) ~/.Eterm/MAIN, which will be a very
+   E-like config file.  See doc/MAIN.dist for a sample.
+ - The config files support $ variable expansion, ~ expansion, single/double
+   quotes, and (if #defined) backquotes.  PLEASE read the accompanying
+   notes in src/feature.h before #defining ALLOW_BACKQUOTE_EXEC.  Also
+   supported is the %include macro.
+
+Changes in DR-0.6a:
+-------------------
+
+ - Lots of bug fixes:
+    - The font options now accept font names starting with '-'
+    - Intense colors are no longer off by one.
+    - Scrollbar and cursor color configuration options now work properly.
+    - Eterm now changes back to the original directory after searching for
+      a config file.
+    - Command line options now take precedence over config file options
+    - -h and --help now work properly, instead of asking for a string value
+    - MAIN.dist.in now contains a value for cut_chars that works right when
+      ALLOW_BACKQUOTE_EXEC is #defined.
+    - The "video reverse" in MAIN.dist.in is now "video normal", because I
+      got sick of people saying there was a bug in Eterm that caused their
+      foreground and background colors to be swapped. :^)  More of a
+      cl00bie-didn't-read-the-comments fix than a bug fix....  ;)
+
+ - New features:
+    - A "magic number"-like identifier that will prevent Enlightenment config
+      files from being read by Eterm.  See doc/MAIN.dist for details.
+    - Secure execution of backquote commands in config files, even if Eterm
+      runs setuid/setgid.
+    - Invalid contexts are skipped entirely with only one error message.  For
+      example, if you don't compile in kanji support, you'll only get one
+      warning instead of 5 or 6.
+    - -H and --home-on-echo options, which will cause Eterm to jump to the
+      bottom of the screen when something is echoed there, if you're viewing
+      the scrollback buffer.  There is also a new attribute "home_on_echo" in
+      the toggles context of the config file for this option.  Thanks to Casey 
+      <casey@netcomi.com> for his help with this.  Just in time, Casey. :)  
+    - There is now a script which randomly chooses a pixmap from ~/.Eterm/pix
+      that can be executed in your config file.  This script requires the
+      dorand program (source provided) and can be found in doc/random_pixmap.sh
+
+Changes in DR-0.7:
+------------------
+
+ - Theme support.  The options were changed to -t and --theme.  Consult the FAQ for
+   more info on themes.
+ - Alternate config file option.  This has been integrated into theme support, but
+   can also work independently thereof.  If you don't like the name MAIN for your
+   config file, or want to run a certain Eterm with a different config file, use
+   the -X or --config-file option.
+ - Borderless Eterm windows.  Use the -x or --borderless option to get a borderless
+   Eterm.  Remember, you'll want to specify a geometry, since you won't be able to
+   move it, and something to exec.  If your window manager supports it, it is
+   recommended that you use that functionality rather than Eterm's built-in option.
+ - Built-in functions.  Several functions have been added to facilitate the building
+   of more robust config files.  The currently-supported functions are:
+     - %appname()         Returns the current application name.  "Eterm-DR-0.7" as of
+                          Eterm 0.7.
+     - %version()         Returns the numeric version.
+     - %random(...)       Randomly chooses one of its parameters and returns that.
+ - Other new options (consult the MAIN file and the --help screen for more info):
+    - -E and --home-on-refresh
+    - --pointer-color
+    - --scrollbar-right
+    - --scrollbar-floating
+    - -M and --menu  (Menubar code is beta, so use it at your own risk)
+    - --term-name
+ - Config file support for all the above.  Also:
+    - exec (context misc)    For use with themes....
+ - Some major and minor bug fixes.  Nobody noticed, so I won't go into details. :)
+ - Support for Window Maker's "docking", thanks to CmdrTaco (Rob Malda)
+   (http://slashdot.org/malda/)
+
+Changes in DR-0.8:
+------------------
+
+ - Several experimental features are in, like active tags, fake transparency,
+   and threads support.  Use them at your own risk; they are unsupported and
+   known not to work right.  We chose not to fix them since we're going to
+   rewrite the whole thing anyway (see http://ganja.tky.hut.fi/resurrection/)
+ - The FORCE_BACKSPACE feature introduce in 0.7 PL5 has been disabled for now;
+   you can't succesfully start Eterm as a background process with it
+ - The new fake transparency option, -O/trans, only works OK with a pixmap
+   the size of your root window / resolution. Test it with an exact image
+   of your root window for a neat effect :) Note that escape sequences for
+   changing the background pixmap will be ignored.
+ - Two new config file options, "trans" and "save_under", have been added.
+   Read themes/Eterm/MAIN for more information. The corresponding new
+   command line options are -O and --save-under.
+ - Fixed the pixmap handling code so that the menubar stuff works right now.
+   Thanks to Cliff Wright <cliff@vixen.itdl.ds.boeing.com> and keebler
+   <keebler@ncal.verio.com> for their help with finding and fixing this.
+ - The Xterm-style scrollbar feature (defined in src/feature.h) will actually
+   compile and run properly.  The restriction on size to 15 pixels has
+   been removed as well.  Thanks to Peter Norby <norby@inktomi.com> and
+   Hal Black <hal@hablack.bevc.blacksburg.va.us> for supplying patches for
+   this.
+ - Made several changes to the configure script so that hopefully it will
+   work for a larger percentage of the populace.  :-)  Some of the changes
+   were suggested by John Reese <jtr@pyro.ugcs.caltech.edu> and Hal Black
+   <hal@hablack.bevc.blacksburg.va.us>.
+ - Added MIN_ANCHOR_SIZE to src/feature.h which allows you to specify a minimum
+   size for the scrollbar anchor.  Good for large scrollback buffers and/or
+   small windows.  Still a mite flaky at the bottom of the scrollbar, but it
+   works.  Credit for the idea goes to Stephen Farrell <stephen@farrell.org>,
+   though the actual code was largely rewritten.
+ - Added CHANGE_SCROLLCOLOR_ON_FOCUS to src/feature.h which makes the
+   scrollbar "disappear" (i.e., become the background color) when the window
+   loses focus.  This feature was suggested by Scott Heavner
+   <sdh@falstaff.MAE.cwru.edu>.
+ - Added option --menu-text-color and config file attribute menu_text,
+   which allow you to change the color of the menubar text.  This feature
+   was suggested by Scott Heavner <sdh@falstaff.MAE.cwru.edu>.
+ - Fixed a bug for FreeBSD that only allowed Eterm to open 16 tty's at
+   once.  Thanks to Christopher Mann <r3cgm@cdrom.com> for finding this
+   one.
+ - PL1
+    - Fixed bug which caused scrollbar not to redraw properly
+ - PL2
+    - Rewrote the string functions in src/misc.c to be faster.  Also, support
+      for "\C" and "C-" to represent the Ctrl-key modifier was added.
+    - Added MENU_TEXT_FLOATING to src/feature.h which puts the menubar text
+      in the middle of the menubar buttons (which is, IMHO, where it belongs,
+      but apparently someone disagrees :-) -- mej).
+    - The pre-release stuff in RELNOTES.Eterm has been removed.
+    - Added an "emacs" theme for GNU Emacs or XEmacs in a text window.
+    - Got rid of that damned annoying preedit type error. :-)
+    - Added call counting for the malloc routines in libmej/mem.* thanks to
+      Michael Wolf (Elessar) <mawolf@concentric.net>.
+ - PL3
+    - Changed themes/Makefile.in so that existing themes in
+      ${prefix}/lib/Eterm/themes do not get overwritten by the "make install"
+      routine.  Sorry, stupid oversight on my part. :(  -- mej
+    - New "chooser" theme.  Read the comments at the top of
+      themes/chooser/chooser.menu for more details. :)
+    - New extended command "echo" in the ESC ] 10 ; set.  See the chooser
+      theme for implementation examples.  Basically, it echoes its parameters
+      and tacks a carriage return on the end.
+    - Fixed the bug introduced in PL2 which caused a border width < the shadow
+      width to not properly display the menubar.  This was only noticeable in
+      the mutt theme or to users who specifically set border_width to 0 or 1.
+    - Eterm now sets the environment variable ETERM_THEME_ROOT to point to the
+      root directory of the theme it is currently using.
+ - PL4
+    - Made several portability improvements in the configure script and its
+      associated files.
+    - Moved the active.tags file into the themes directory, which is the
+      location from which it is installed.
+    - The configure script now builds src/feature.h instead of the make process
+      so that it will be there before the make is done.  If src/feature.h.in is
+      updated, however, src/feature.h will still be generated from it by a make.
+    - The installed Eterm binary will be Eterm-<version_number>, and Eterm will
+      be created as a soft-link to that file in the $bindir directory.
+    - Eterm will now guess the install prefix (${prefix}) based on where gcc is
+      located, unless you give a --prefix on the command line.  This keeps me
+      from having to use it.  If it makes you have to use it, tough break. =P
+    - Added the --with-imlib option to configure.  If you specify
+      --with-imlib=/some/path, the compiler will look in /some/path/include
+      for Imlib's header files and in /some/path/lib for Imlib itself.  You can
+      also specify --without-imlib, which will disable pixmap support entirely.
+ - PL5
+    - Fixed the problem with the Eterm -> Pixmap -> None menu item.
+    - IMPORTANT NOTE:  One of the src/feature.h defines added in version 0.8 was
+      the MIN_ANCHOR_SIZE #define.  There are KNOWN PROBLEMS with using this feature
+      and trying to scroll up from the bottom using Shift-Prior, the up arrow on the
+      scrollbar, etc.  If this bothers you, COMMENT OUT that line in src/feature.h.
+      Fixing this problem will require a redesign of how Eterm looks at scrolling
+      and positioning the terminal window relative to the scrollbar and vice versa.
+      This may or may not happen in the current development cycle.
+    - Added the CTRL_CLICK_RAISE #define to src/feature.h which allows a mouse
+      click in the terminal window while holding the Ctrl key to raise the window
+      and steal keyboard focus.  This is useful if you are stuck without a window
+      manager for one reason or another or for using Eterm as an X session manager.
+    - Also added an escape sequence, ESC ] 5 ; BEL, to perform the same task, and
+      added a menu item called "Steal Focus" to send that escape sequence.
+    - Fixed the "bug" that made command-line paths relative to the current theme
+      as well as paths in theme config files.  Searching relative to the current
+      directory takes place after searching the directories in the "path" line
+      (from the config file).  (I have "bug" in quotes because it wasn't really
+      a bug -- all paths were interpreted relative to the theme used -- but it
+      applied to command-line variables too, which was very confusing to some.)
+
+Changes in 0.8.6:
+-----------------
+
+ - For starters, we changed the naming convention.  No more "DR" and "PL" stuff.
+   We got asked too many stupid questions.  ("What's the P 15 mean?")  Starting
+   with this release, we'll be using numbers only.  The third number will still
+   indicate the patch level, however.
+ - Added support for imlib-config script supplied with Imlib 1.8 and up.  This
+   speeds and simplifies the calculation of CFLAGS and LDFLAGS for proper
+   linking with Imlib.
+ - Fixed problems with compilation on NetBSD thanks to Clifford Wright
+   <cliff@snipe444.org>.
+ - Redid the themes to support the new pixmap mechanism I'm working on.  Once
+   the new pixmap archive comes out, you'll want to remove your themes
+   directory ($prefix/lib/Eterm/themes by default) and install the themes
+   contained in this distribution.  Get the new Eterm Backgrounds Collection
+   at http://www.tcserv.com/archive/E/ or a mirror near you.
+ - Reworked the transparency mechanism thanks to Gerald Britton
+   <gbritton@mit.edu> and Nat Friedman <ndf@mit.edu>.  It now takes a copy
+   of the root window's pixmap and uses that.  It responds to all moves and
+   resizes by updating the pixmap.  No requests for changing pixmap are
+   honored by a transparent Eterm (the -O or --trans options).  Furthermore,
+   this will probably only work in Enlightenment.  And for the full effect,
+   you'll want to run it without scrollbar/menubar and borderless (the
+   latter being done either through Enlightenment or with the -x option).
+ - Added the Esetroot program, which sets the root pixmap atom for those
+   who don't use Enlightenment as their window manager.  There has been
+   mixed feedback on whether or not this program works.  YMMV.
+ - Added a theme to demo some of the pseudo-transparency features.  Use
+   "Eterm -t trans" to invoke it.
+ - Some pseudo-transparency toys are in too.  The option --shade will darken
+   the portion of the desktop "showing through" the Eterm window.  Results
+   in a "smoked glass" effect.  This option can also be used with the
+   --tint option to provide a colored glass effect.  See the man page for
+   more information.  Also be sure to check out the effect of the
+   --scrollbar-floating option with transparency. :)
+ - Fixed compilation without pixmap and/or menubar support.  The options
+   --disable-menus and --without-imlib can, when passed to the configure
+   script, be used to automatically disable menubar and pixmap support,
+   respectively.
+ - NEW MAN PAGE!!  At long last, the man page has been updated with the new
+   options.  Many thanks to Shaleh <shaleh@debian.org> for doing this.
+ - The values "yes" and "no" can now be used as boolean values in options
+   and config file entries, along with 0/1, true/false, and on/off.
+ - Eterm now changes the color of the scrollbar when losing focus.  If no
+   unfocused scrollbar color is specified in the config file or on the
+   command line, you will not notice it.  See the man page and the default
+   config files for more info.
+
+Changes in 0.8.7:
+-----------------
+
+ - The old libmej is now built as a shared library as well as a static one.
+   Also, everything but the main() function has been moved into a library,
+   libEterm.  Since most people use lots of Eterms at once, creating a shared
+   library will reduce the text segment of each Eterm significantly, saving
+   quite a bit of memory per Eterm.
+ - Removed MIN_ANCHOR_SIZE and added -a (--min-anchor-size) option.  It is 0 by
+   default so ppl won't complain about the scroll-up "bug".
+ - Lots of fixes to Esetroot
+ - CygWin32 support.  May take a little bit of effort, but it works.
+ - Escape sequences to toggle transparency and shading, as well as set tint,
+   are in.  Toggling transparency works.  The others don't yet.
+ - Newer Linux versions required a hack to open the display.
+ - Cleaned up privileges toggling.
+ - Changed the --watch-bg option to --watch-pixmap, which will hopefully make it
+   less tempting for people to think it has something to do with transparency.
+ - Added the --watch-desktop option which causes a pseudo-transparent Eterm to
+   monitor the desktop pixmap for changes and update accordingly.
+ - Several various parser cleanups.
+ - Transparency can now be done via Imlib rather than Xlib.  It is markedly slower
+   but offers more configureability, like shading by percentage (--shade-pct) and
+   tinting masks (--tint <24-bit mask>).
+ - Shading now works for 8bpp pseudo-color displays.  This formerly generated an
+   error message about the X server not setting the visual info properly.  It is
+   not fast by any means, but that's what you get for having an 8bpp video card.
+ - Fixed the menubar code so that the menus aren't clipped by the window or screen
+   edge.
+ - Changed the shell_expand() function in options.c so that \' within single quotes
+   would insert a single quote.  This differs from the shell behavior, but I prefer
+   it. :)
+ - More *BSD utmp fixes.
+ - Added debugging features configureable at configure-time.  Also added stack
+   tracing on crash.
+ - Fixed the bug with dragging a transparent Eterm across E's desktop dragbar.  It
+   reparents to the root window for a bit, but once you drop the window, it changes
+   backdrops right on cue.  Also works when moving Eterm windows between desktops.
+   Note that this requires the use of the -W (--watch-desktop) option.
+ - \e[9n prints the pixmap filename in the title bar.  In transparency mode, prints
+   transparency info to the title bar.
+ - New --home-on-input option which split off part of --home-on-echo
+
+Changes in 0.8.8:
+-----------------
+
+ - Better, more detailed man page.  Now if only people would read it....
+ - Shading is now done by percentage, and tinting by hex mask.  See the man page for
+   more info.
+ - Lots of new options:  --menubar-move, --anim, --pause, --viewport-mode,
+   --xterm-select, and --select-line.  See man page for details.
+ - FORCE_BACKSPACE and FORCE_DELETE have been fixed.
+ - KS_DELETE (the strings associated with pressing the Delete key) is now set to ^?
+   by default.  If you don't like that, you can set it back, or use the keysym
+   attribute in the config file, or whatever.
+ - --with-cc=prog argument to ./configure to specify an alternative compiler.  The
+   default looks for egcs, then pgcc, then gcc, etc.
+ - Eterm-specific escape sequences:
+       Syntax:  ESC ] 6 ; <op> ; <arg> BEL
+
+       where <op> is:  0    toggle transparency
+	               1    set shade percentage
+		       2    set tint mask
+		       3    forced update of pseudo-transparent background
+		      30    Do not use
+		      40    Do not use
+       and <arg> is an optional argument, depending
+       on the particular sequence being used.  It
+       (along with its preceeding semicolon) may or
+       may not be needed.
+ - X errors are handled more gracefully and with more helpful information.
+ - The --disable-stack-trace option to ./configure, whose use is obvious.
+ - Added an icon and associated option/attribute.
+ - As always, lots of bug fixes.  See the ChangeLog for details.
+ - The -center option for Esetroot.  Centers the pixmap.
+ - Eterm is now FHS compliant, meaning that the theme and image directories are
+   now under ${prefix}/share/Eterm instead of ${prefix}/lib/Eterm.  See the
+   move-themes script included in the distribution.
+
+Changes in 0.8.9:
+-----------------
+
+ - Support for scrolling with mouse wheels.
+ - New --version switch to display compile-time configuration.
+ - Tinting and shading have been sped up by about 30% thanks to Michael Pearson
+   <alcaron@ozemail.com.au>.
+ - Scrollbar type and width is now customizeable at compile-time *and* run-time.
+   Support for NeXT-style scrollbars has also been added.
+ - Three *major* bugs have been fixed.  Tiled desktop images no longer cause
+   crashes when tinting or shading.  The resize crash bug has also been squished.
+   The secure system() call replacement which was accidentally removed has been
+   added back.
+ - Ctrl-Button1 now grabs input focus.  Ctrl-Button2 toggles the scrollbar on and
+   off.  Ctrl-Button3 toggles the menubar on and off.  NOTE:  If you used to
+   disable the menubar by commenting out the loading of the menubar file, or
+   loading a fake one (e.g., '-Mx' or '-M /dev/null'), don't.  Simply add "off" to
+   the end of the menu line (e.g., 'menu Eterm.menu off'), or use the new boolean
+   command-line option --menubar (e.g., '--menubar off').  Then you can toggle the
+   menubar using Ctrl-Button3 like you would expect.
+ - Popup scrollbar support has been added.
+ - New -D (--desktop) option for choosing a desktop to start on.  Your window
+   manager must be GNOME-compliant for this to work.  See the documentation at
+   http://www.gnome.org/devel/gnomewm/ for info on the _WIN_WORKSPACE property.
+ - The Eterm Technical Reference has been completely rewritten.  It is now an HTML
+   document located in the doc/ directory.
+ - Lots and lots and lots of new escape sequences.  See the Technical Reference for
+   details on them.
+ - Oodles of small bug fixes, as always. :-)
+ - Debugging output is now runtime configurable.  Use the --debug option and supply
+   a number.  0 (the default) gives no debugging output.  1-5 give increasingly
+   more output, up to 5 (which I don't recommend using) which synchronizes X events
+   (and slows things down bigtime).
+ - You can now save your current Eterm settings from the menu.
+ - New --app-keypad and --app-cursor options to set the startup mode for
+   application/normal mode for the keypad and cursor keys.
+ - Three new utilities in addition to Esetroot, all of which are located in the
+   utils/ directory.  Etbg is a tool for manipulating Eterm's background image on
+   the fly.  Etcolors.sh demonstrates all the different combinations of your
+   current color settings.  Etmenu.sh lets you send menu commands to Eterm's
+   menubar subsystem without having to type the escape codes yourself.
+ - Borderless Eterms now attempt to use the Window Manager to become borderless
+   instead of bypassing it altogether.
