#
# The list of aggregate project directory names is in the makefile
# variable SUBPROJECTS. The name is unforunate, because it is confusingly
# similar to xxx_SUBPROJECTS, which is used for subprojects.
#
# SUBPROJECTS - which is implemented in this file - are just a list of
# directories; we step in each directory in turn, and run a submake in
# there. The project types in the directories can be anything -
# tools, documentation, libraries, bundles, applications, whatever.
# For example, if your package is composed by a library and then by
# some tools using the library, you could have the library in one
# directory, the tools in another directory, and have a top level
# GNUmakefile which has the two as SUBPROJECTS.
#
# xxx_SUBPROJECTS - which is *not* implemented in this file, I'm just
# explaining it here to make clear the difference - are again a list
# of directories, each of which should contain a *subproject* project
# type (as implemented by subproject.make), which builds stuff into a
# .o file, which is then automatically linked into the xxx instance by
# gnustep-make when the top-level xxx is built. For example, a
# library might be broken into many separate subprojects, each of
# which implementing a logically separated part of the library; the
# top-level GNUmakefile will then build the library, specifying
# xxx_SUBPROJECTS for the library to be those directories.
# gnustep-make will step in all dirs, compile the subprojects, and
# then finally automatically link the subprojects into the main
# library.
