# This script enables you to rapidly fetch or update 'src', 'ports' and
# xenocara trees, compile a new kernel, the userland or xenocara and install
# this new kernel.
#
# Simply put the script in your ~/bin.
# Usage is:
#
# # maj -g [src|ports|xenocara|all]	Get tree, ports, xenocara or all
# # maj -u [src|ports|xenocara|all]	Update tree, ports, xenocara or all
# # maj -c [kernel|uland|xenocara]	Compile kernel, userland or xenocara
# # maj -i				Install new kernel from /usr/src
# # maj -r				Create release tarballs
#
# WARNING : before running this script, don't forget to put your nearest
# OpenBSD Anonymous CVS Server.
#
# CVS repository
