# Top Level "Diabolical" EPICS Makefile
#        by Matthew Needes and Mike Bordua
#
#  Notes:
#    The build, clean, install, and depends "commands" do not have
#         their own dependency lists; they are instead handled by
#         the build.%, clean.%, etc. dependencies.
#
#    However, the release dependencies DOES require a complete
#         install because the release.% syntax is illegal.
#
#    If TOUCH=Y is included on the make command line, flags will
#         be touched to indicate that a certain portion of the build
#         is complete.

#  Notes for single architecture build rules:
#    CheckArch only has to be run for dirs.% .  That
#    way it will only be run ONCE when filtering down
#    dependencies.
#
#  CheckArch does not have to be run for cleans
#    because you might want to eliminate binaries for
#    an old architecture.

#  Create dependencies for an architecture.  We MUST
#     do this separately for each architecture because
#     some things may be included on a per architecture 
#     basis.
