# Author Matthew Turk <satai@gentoo.org>
#
# This eClass is designed to be easy to use and implement.  The vast majority of
# LaTeX packages will only need to define SRC_URI (and sometimes S) for a
# successful installation.  If fonts need to be installed, then the variable
# SUPPLIER must also be defined.
#
# However, those packages that contain subdirectories must process each
# subdirectory individually.  For example, a package that contains directories
# DIR1 and DIR2 must call latex-package_src_compile() and
# latex-package_src_install() in each directory, as shown here:
#
# src_compile() {
#    cd ${S}
#    cd DIR1
#    latex-package_src_compile
#    cd ..
#    cd DIR2
#    latex-package_src_compile
# }
#
# src_install() {
#    cd ${S}
#    cd DIR1
#    latex-package_src_install
#    cd ..
#    cd DIR2
#    latex-package_src_install
# }
#
# The eClass automatically takes care of rehashing TeX's cache (ls-lR) after
# installation and after removal, as well as creating final documentation from
# TeX files that come with the source.  Note that we break TeX layout standards 
# by placing documentation in /usr/share/doc/${PN}
#
# For examples of basic installations, check out app-text/latex-aastex and
# app-text/latex-leaflet.
#
# NOTE: The CTAN "directory grab" function creates files with different MD5
# signatures EVERY TIME.  For this reason, if you are grabbing from the CTAN,
# you must either grab each file individually, or find a place to mirror an
# archive of them.  (iBiblio)
