dnl AC_E_OPTIONAL_MODULE(name, [initial-status, [check-if-enabled]])
dnl Defines configure argument --<enable|disable>-[name] to enable an
dnl optional module called 'name'.
dnl
dnl If initial-status is true, then it's enabled by default and option
dnl will be called --disable-[name], otherwise it's disabled and option
dnl is --enable-[name].
dnl
dnl If module is enabled, then check-if-enabled will be executed. This
dnl may change the contents of shell variable NAME (uppercase version of
dnl name, with underscores instead of dashed) to something different than
dnl "true" to disable module.
dnl
dnl Parameters:
dnl - name: module name to use. It will be converted to have dashes (-)
dnl instead of underscores, and will be in lowercase.
dnl - initial-status: true or false, states if module is enabled or
dnl disabled by default.
dnl - check-if-enabled: macro to be expanded inside check for enabled
dnl module.
dnl
dnl Provides:
dnl - USE_MODULE_[name]=true|false [make, shell]
dnl - USE_MODULE_[name]=1 if enabled [config.h]
