well as this is very inspired from texlive install-pkg.sh script, I'd
prefer not differing that much.

changed that one, the "semantics" looks better indeed; what is wanted
here is to exclude $f containing "config". Am I missing something when
I understand it as the exact same thing but more readable ?

thanks, too much influence from other programming languages...


Attached try3, with some more comments on the functions of
texlive-module.eclass.

# Ebuilds have to provide TEXLIVE_MODULE_CONTENTS variable that contains the list
# of packages that it will install.
# TEXLIVE_MODULE_CONTENTS will be expanded to SRC_URI :

# What is assumed is that it unpacks texmf and texmf-dist directories to
# ${WORKDIR}.
