# @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)
