+# @BLURB: Provide generic install functions so that modular texlive's texmf ebuild will only have to inherit this eclass
+# @DESCRIPTION:
+# 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. (See below)
+#
+# For TeX Live versions prior to 2009, the ebuild was supposed to unpack the
+# texmf and texmf-dist directories to ${WORKDIR} (which is what the default
+# src_unpack does).
+# Starting from TeX Live 2009, the eclass provides a src_unpack function taking
+# care of unpacking and relocating the files that need it.
+#
+# It inherits texlive-common. Patching is supported via the PATCHES
+# bash array.
+
+# @ECLASS-VARIABLE: TEXLIVE_MODULE_CONTENTS
+# @DESCRIPTION:
+# The list of packages that will be installed. This variable will be expanded to
+# SRC_URI:
+# foo -> texlive-module-foo-${PV}.tar.xz
+
+# @ECLASS-VARIABLE: TEXLIVE_MODULE_DOC_CONTENTS
+# @DESCRIPTION:
+# The list of packages that will be installed if the doc useflag is enabled.
+# Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.
+
+# @ECLASS-VARIABLE: TEXLIVE_MODULE_SRC_CONTENTS
+# @DESCRIPTION:
+# The list of packages that will be installed if the source useflag is enabled.
+# Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.
+
+# @ECLASS-VARIABLE: TEXLIVE_MODULE_BINSCRIPTS
+# @DESCRIPTION:
+# A space separated list of files that are in fact scripts installed in the
+# texmf tree and that we want to be available directly. They will be installed in
+# /usr/bin.
+
+# @ECLASS-VARIABLE: TEXLIVE_MODULE_BINLINKS
+# @DESCRIPTION:
+# A space separated list of links to add for BINSCRIPTS.
+# The systax is: foo:bar to create a symlink bar -> foo.
+
+# @ECLASS-VARIABLE: TL_PV
+# @DESCRIPTION:
+# Normally the module's PV reflects the TeXLive release it belongs to.
+# If this is not the case, TL_PV takes the version number for the
+# needed app-text/texlive-core.
+
+# @ECLASS-VARIABLE: TL_MODULE_INFORMATION
+# @DESCRIPTION:
+# Information to display about the package.
+# e.g. for enabling/disabling a feature
+
+# @ECLASS-VARIABLE: PATCHES
+# @DESCRIPTION:
+# Array variable specifying any patches to be applied.
