+extras for Gem
+==============
+
+this folder contains objectclasses that are shipped with Gem but are not linked
+into Gem.
+
+reasons why these objectclasses are not part of Gem proper are:
+
+- license issues
+  (Gem is GPL, objects that are not GPL would go in here)
+
+- dependency issues
+  (we try to keep the dependencies of Gem-core to the minimum of openGL and
+   WindowManager (if at all); any objectclass that makes heavy use of 3rd party
+   libraries would go in here)
+
+- specialist objects
+  (objectclasses that are highly specialized and of no common interest might go
+   in here as well)
+
+
+
+ADDING your own subdirectory to extra/ using autoconf:
+- Gem/extra/Makefile.am
+	add your projects to the SUBDIRS variable
+	if your project has a "Makefile" that has all the usual autoconf
+	targets, you are done :-)
+	see Gem/extra/Makefile.am for an example
+	.
+	this applies to most projects!
+
+- Gem/configure.ac
+	if you provide a Makefile.am and want Gem's build process to create a
+	Makefile from that, you have to add [extra/<project>/Makefile] to the
+	AC_CONFIG_FILES in Gem/configure.ac;
+	see Gem/configure.ac for an example
+	.
+	this applies to small projects (no additional dependencies) that are
+	to be shipped with Gem
+
+- Gem/extra/configure.ac
+	if you provide your own autoconf system (configure.ac), add your project
+	to the AC_CONFIG_SUBDIRS in Gem/extra/configure.ac
+	see Gem/extra/configure.ac for an example
+	.
+	this applies to bigger projects (additional dependencies) or projects
+	not to be shipped with Gem
+
