# 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_BRANCH        - Branch tag to use for checkout (default: HEAD)
