# Makefile.DEPS
#
# Automatically generate depends without actually building anything
# This is used for maintainers who won't or can't build all
# parts of a project before running make dist.
#
# Note this is only needed for automake 1.4 and requires gcc.
# If you're using automake 1.5, throw this monstrosity out!
# This is a gross hack, you really should NOT use this.
#
# YOU REALLY SHOULD NOT USE THIS
