# The Netpbm make files exploit features of GNU Make that other Makes
# do not have.  Because it is a common mistake for users to try to build
# Netpbm with a different Make, we have this make file that does nothing
# but tell the user to use GNU Make.

# If the user were using GNU Make now, this file would not get used because
# GNU Make uses a make file named "GNUmakefile" in preference to "Makefile"
# if it exists.  Netpbm is shipped with a "GNUmakefile".
