# snacc is needed to generate the distfiles
#
# Revision 1.8  1997/02/16 12:34:47  rj
# let make clobber remove the link to install-sh that make made
# let make clean remove more created files
#
# Revision 1.7  1997/01/02 08:47:20  rj
# an option to snacc added (when compiling the tbl.asn1 file)
#
# Revision 1.6  1995/07/25  18:09:18  rj
# the compiler is compiled from two files, tbl.h and tbl.c, it generates itself.
# for bootstrapping purposes, initial versions are supplied with the distribution.
#
# `cd && make' instead of `cd; make'.
#
# create installation directories only if they do not exist already.
