# Makefile to create LPRng, ifhp, and LPRngTool
#  targets:
#   make all       - does unpack, configure, build
#     make unpack    - untars the latest releases, creates symlinks to distributions
#     make configure - does configure in distributions, create .configured in subdirectory
#     make build     - does a make all in the subdirs 
#   make install     - does a make install in the subdirs 
#                           and some fixup of files
#   make printcap    - cd PRINTCAP and makes/installs new printcap...
#                      see PRINTCAP/Makefile for details
#   make lpd.perms lpd.conf - cd to LPD_PERMS, LPD_CONF and does install
#                      - lpd.perms is usually the only thing needed
#   make clean     - does a make clean in the subdirs
