# We make sure that all the interesting paths in all domains are
# defined.  Having this is a great help in iterating over header dirs,
# for example.
#
# PS: If you change this list, make sure that top update the list of
# paths used in common.make when GNUSTEP_INSTALLATION_DIR is set.

#
# We use '?=' to only set variables that have not already been set by
# the user in the config files (that should be read before this file).
# So, this describes the GNUstep filesystem default that is
# automatically used when the config file is missing some settings.
#
# Some directories are fixed to be subdirectories of Library.
#
# We keep the list in this simple format (instead of generating it
# from functions, for example) to make it very easy to read for
# everyone.
