# Build the Mozilla client.
#
# This needs CVSROOT set to work, e.g.,
#   setenv CVSROOT :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot
# or
#   setenv CVSROOT :pserver:username%somedomain.org@cvs.mozilla.org:/cvsroot
# 
# To checkout and build a tree,
#    1. cvs co mozilla/client.mk
#    2. cd mozilla
#    3. gmake -f client.mk
#
# Other targets (gmake -f client.mk [targets...]),
#    checkout
#    build
#    clean (realclean is now the same as clean)
#    distclean
#
# See http://www.mozilla.org/build/unix.html for more information.
#
# Options:
#   MOZ_OBJDIR           - Destination object directory
#   MOZ_CO_DATE          - Date tag to use for checkout (default: none)
#   MOZ_CO_MODULE        - Module to checkout (default: SeaMonkeyAll)
#   MOZ_CVS_FLAGS        - Flags to pass cvs (default: -q -z3)
#   MOZ_CO_FLAGS         - Flags to pass after 'cvs co' (default: -P)
