-# The following are config.in's which are generated, to avoid numerous manual edits when
-# adding packages to the build.
-#
-# NOTE: There currently exists a bug regarding this, the toplevel config.in -must- be created
-# -after- the lower level config.ins, as makecfg.pl does a find for config.in files!
-#
-#  solution: generate this list and stuff into .depends, and also
-#  generate config.in interdependencies (i.e. topdir config.in depends on
-#    config.ins within dirs below it. dependencies are solely dir structure
-#    driven)
