# GRASS source code cleaning options:
#
# There are three options for cleaning the GRASS source code. Each option
# performs the following operations:
#
# make clean     - delete all object files and the next step file, keep the
#                  compiled GRASS libraries - good for saving disk space
# make distclean - delete object files, next step file, libraries, and
# 		   generated directories like etc/ and dev/ - good for
#                  recompiling on the same system (keep configure files)
# make veryclean - delete object files, next step file, libraries, generated
#                  directories, head file, configure files, and Makefile - good
#                  for starting the whole installation from scratch
#
# Note that some files may not be deleted due to difficulties in specifying
# them in this Makefile. These files include the C files generated by lex and
# yacc, and any other file that is not listed in the options above.
