# This file is used to compile miscellaneous 'plt'-related stuff. See
# '../INSTALL'.

# ----------------------------------------------------------------------------
# Site-dependent variables:

# The values of these variables are normally set in ../Makefile -- change them
# there if necessary.

# PREFIX is the root of the tree into which the plt package is ultimately
# installed.
PREFIX=/usr/local

# INSTALL_PREFIX is usually the same as PREFIX, but 'rpm' or 'rpmbuild' resets
# it to the root of a temporary build tree when making a set of RPMs.
INSTALL_PREFIX=$(PREFIX)

# BINDIR is the directory into which the executables and shell scripts are
# to be installed.  You must have write permission in BINDIR to complete the
# installation successfully.
BINDIR = $(INSTALL_PREFIX)/bin

# It should not be necessary to modify anything below this line.
# ----------------------------------------------------------------------------

# `make all' (or just `make') compiles the targets but does not install them.
# You must have write permission in this directory, but nothing more is needed.

	@echo "    make install"

# `make install' compiles the targets if necessary, then installs them.
