Makefile

# Generic GNU Makefile with Native Language Support
# written by Henrik Carlqvist
# 
# Possible targets are:
# make                    normal compile
# make all                normal compile, the same as above
# make install            installs compiled files
# make uninstall          removes installed files
# make clean              removes compiled files
# make mrproper           removes compiled files and dependencies
# make debug              compiles with flag -g for debuggers
# make messages           creates po/messages.po as a skeleton for NLS
