#  Prepare xz-compressed tarballs of texlive-texmf-trees based on texlive.tlpdb
#  This script takes care of dependencies(as far as these are present in texlive.tlpdb)
#  of collections and packages, and that every texlive-package is included only once.
#  The editions(base/extra/docs) should contain no binaries(exception biber)
# -base: the most usefull stuff, most binaries/scripts,
#  manpages for compiled binaries  65mb 2017-11-07
# -docs: -base documentation only, no manpages/GNU infofiles
# -extra: remaining stuff
#
#  texlive netarchive policy: Every package is included as dependency 
#  in exactly one collection. A package may have dependencies on other
#  packages from any collection.

# package source: http://mirror.ctan.org/systems/texlive/tlnet/archive/
