# For this reason, long term we'd like to replace the variable
# SUBPROJECTS with the variable AGGREGATE_PROJECTS. As of February
# 2010, we can't just do it without breaking all GNUmakefiles. So in
# February 2010, we added AGGREGATE_PROJECTS, so that gnustep-make now
# recognizes AGGREGATE_PROJECTS as well as SUBPROJECTS. In a few
# years, when everyone is using a version of gnustep-make that does
# this, we can deprecate SUBPROJECTS and tell everyone to switch to
# AGGREGATE_PROJECTS without breaking anything :-) In other words, the
# following three lines of code are for compatibility with future
# versions of gnustep-make where the variable will be named
# AGGREGATE_PROJECTS.
