# Each line is of the form:
#
#  name_of_depenency: <distro_chars>:package [<distro_chars>:package...]
#
# The dependency name is purely informative and isn't otherwise used. distro_chars are:
#
#  f: Fedora
#  d: Debian/Ubuntu
#  s: SuSE
#  m: Mandriva
#
# Rather than have some complicated system here, when we have packages that depend
# on distribution version, we just tweak the package list in the code below.
# Where known, the module that requires a library is commented.
