#
# Central makefile. Descends all source directories, making recursively.
#
# Targets:
#
#  all       - make all libraries, then all applications
#  cvs       - add all cpp h and Makefile files to cvs
#  lib       - make all libraries
#  app       - make all applications
#  clean     - clean all library directories and app directories.
#  this removes only files pertaining to the current platform and
#        target (release/debug). This also removes generated libraries.
#  distclean - removes all build directories. 
#  platform  - copies a template to OS_CPU_COMPILER.mk in the makefiles
#                       directory
