# Written by Jim Van Zandt <jrv@vanzandt.mv.com>, borrowing heavily
# from the install scripts for gettext by Santiago Vila
# <sanvila@ctv.es> and octave by Dirk Eddelbuettel <edd@debian.org>.
#
# Patched by Roland Mas <lolando@debian.org> to add support for lists of
# flavor-dependently included/excluded files and by Peter S Galbraith
# <psg@debian.org> to add a STAMPFILE (to only byte-compile once) and
# APPEND_LOAD_PATH ton augment the load-path for byte-compilation.
