# @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 ${WORKDIR} (which is what the default
# src_unpack does).
# Starting from TeX Live 2009, the eclass provides a src_unpack function taking
# care of unpacking and relocating the files that need it.
#
# It inherits texlive-common. Patching is supported via the PATCHES
# bash array.
# @ECLASS_VARIABLE: TEXLIVE_MODULE_CONTENTS
# @PRE_INHERIT
# @REQUIRED
# @DESCRIPTION:
# The list of packages that will be installed. This variable will be expanded to
# SRC_URI:
# foo -> texlive-module-foo-${PV}.tar.xz
# @ECLASS_VARIABLE: TEXLIVE_MODULE_DOC_CONTENTS
# @PRE_INHERIT
# @REQUIRED
# @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
# @PRE_INHERIT
# @REQUIRED
# @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
# @DEFAULT_UNSET
# @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
# @DEFAULT_UNSET
# @DESCRIPTION:
# A space separated list of links to add for BINSCRIPTS.
# The syntax is: foo:bar to create a symlink bar -> foo.
# @ECLASS_VARIABLE: TL_PV
# @INTERNAL
# @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
# @DEFAULT_UNSET
# @DESCRIPTION:
# Information to display about the package.
# e.g. for enabling/disabling a feature
