# Note for people building binary packages of nhc98:
# The variable INSTALLDIR, default /usr/local, changed with --prefix=
# gives the final destination of everything.  The configure script
# hard-wires this path into scripts when you give the --install flag.
# However, if you set the environment variable DESTDIR, the installation
# process will still hardwire your INSTALLDIR into scripts, but actually
# install the files in $DESTDIR$INSTALLDIR.  In this way, you can build
# a complete installation tree in a temporary directory, then tar it up
# as a package with all the scripts pointing to the correct final location.
