10 # @BLURB: Provide generic install functions so that modular texlive's texmf ebuild will only have to inherit this eclass
11 # @DESCRIPTION:
12 # Purpose: Provide generic install functions so that modular texlive's texmf ebuilds will
13 # only have to inherit this eclass.
14 # Ebuilds have to provide TEXLIVE_MODULE_CONTENTS variable that contains the list
15 # of packages that it will install. (See below)
16 #
17 # For TeX Live versions prior to 2009, the ebuild was supposed to unpack the
18 # texmf and texmf-dist directories to ${WORKDIR} (which is what the default
19 # src_unpack does).
20 # Starting from TeX Live 2009, the eclass provides a src_unpack function taking
21 # care of unpacking and relocating the files that need it.
22 #
23 # It inherits texlive-common.
24
25 # @ECLASS-VARIABLE: TEXLIVE_MODULE_CONTENTS
26 # @DESCRIPTION:
27 # The list of packages that will be installed. This variable will be expanded to
28 # SRC_URI:
29 #
30 # For TeX Live 2008: foo -> texlive-module-foo-${PV}.tar.lzma
31 # For TeX Live 2009: foo -> texlive-module-foo-${PV}.tar.xz
32
33 # @ECLASS-VARIABLE: TEXLIVE_MODULE_DOC_CONTENTS
34 # @DESCRIPTION:
35 # The list of packages that will be installed if the doc useflag is enabled.
36 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS. This is only
37 # valid for TeX Live 2008 and later.
38
39 # @ECLASS-VARIABLE: TEXLIVE_MODULE_SRC_CONTENTS
40 # @DESCRIPTION:
41 # The list of packages that will be installed if the source useflag is enabled.
42 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS. This is only
43 # valid for TeX Live 2008 and later.
44
45 # @ECLASS-VARIABLE: TEXLIVE_MODULE_BINSCRIPTS
46 # @DESCRIPTION:
47 # A space separated list of files that are in fact scripts installed in the
48 # texmf tree and that we want to be available directly. They will be installed in
49 # /usr/bin.
50
51 # @ECLASS-VARIABLE: TL_PV
52 # @DESCRIPTION:
53 # Normally the module's PV reflects the TeXLive release it belongs to.
54 # If this is not the case, TL_PV takes the version number for the
55 # needed app-text/texlive-core.
