+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]
