# @BLURB: An eclass for easy installation of LaTeX packages
# @DESCRIPTION:
# 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 dev-tex/aastex and
# dev-tex/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)
