+# Original Author: Alexis Ballier <aballier@gentoo.org>
+# Purpose: Provide generic install functions so that modular texlive's texmf ebuilds will
+# only have to inherit this eclass.
+# Ebuilds have to provide TEXLIVE_MODULE_CONTENTS variable that contains the list
+# of packages that it will install.
+# TEXLIVE_MODULE_CONTENTS will be expanded to SRC_URI : 
+#	foo -> texlive-module-foo-${PV}.zip
+# What is assumed is that it unpacks texmf and texmf-dist directories to
+# ${WORKDIR}.
+#
+
+inherit texlive-common

+# sandbox
+# The next step is to generate config files that are to be installed in

+# files for different packages in a single one used by the whole tex installation.
