# procps Makefile
# Albert Cahalan, 2002
#
# Recursive make is considered harmful:
# http://google.com/search?q=%22recursive+make+considered+harmful%22
#
# For now this Makefile uses explicit dependencies. The project
# hasn't grown big enough to need something complicated, and the
# dependency tracking files are an ugly annoyance.
#
# This file includes */module.mk files which add on to variables:
# FOO += bar/baz
