11 # @BLURB: An eclass for easy installation of LaTeX packages
12 # @DESCRIPTION:
13 # This eClass is designed to be easy to use and implement.  The vast majority of
14 # LaTeX packages will only need to define SRC_URI (and sometimes S) for a
15 # successful installation.  If fonts need to be installed, then the variable
16 # SUPPLIER must also be defined.
17 #
18 # However, those packages that contain subdirectories must process each
19 # subdirectory individually.  For example, a package that contains directories
20 # DIR1 and DIR2 must call latex-package_src_compile() and
21 # latex-package_src_install() in each directory, as shown here:
22 #
23 # src_compile() {
24 #    cd ${S}
25 #    cd DIR1
26 #    latex-package_src_compile
27 #    cd ..
28 #    cd DIR2
29 #    latex-package_src_compile
30 # }
31 #
32 # src_install() {
33 #    cd ${S}
34 #    cd DIR1
35 #    latex-package_src_install
36 #    cd ..
37 #    cd DIR2
38 #    latex-package_src_install
39 # }
40 #
41 # The eClass automatically takes care of rehashing TeX's cache (ls-lR) after
42 # installation and after removal, as well as creating final documentation from
43 # TeX files that come with the source.  Note that we break TeX layout standards
44 # by placing documentation in /usr/share/doc/${PN}
45 #
46 # For examples of basic installations, check out dev-tex/aastex and
47 # dev-tex/leaflet .
48 #
49 # NOTE: The CTAN "directory grab" function creates files with different MD5
50 # signatures EVERY TIME.  For this reason, if you are grabbing from the CTAN,
51 # you must either grab each file individually, or find a place to mirror an
52 # archive of them.  (iBiblio)

54 # It inherits base.
