# These macros are used for descending into various subdirectories.
# 
# The general idea of these macros is that we want make to descend into
# every subdirectory of the current directory except for certain ones
# that are skipped.  The different macros have different criteria for
# determining which ones are skipped.
# 
# In all cases the "listdirs" script in the tools directory is used to
# generate a list of directories to consider.  This script returns all
# subdirs of the current dir except certain ones that we never want to
# go into (see the comments in that script for details).
# 
# In addition, all the macros below test to make sure that a directory
# contains a Makefile (with a capital M) before desending into it.
#
