-# Build a mozilla application.
-#
-# To checkout and build a tree,
-#    1. cvs co mozilla/client.mk
-#    2. cd mozilla
-#    3. create your .mozconfig file with
-#       mk_add_options MOZ_CO_PROJECT=suite,browser,mail,minimo,xulrunner
-#    4. gmake -f client.mk 
-#
-# This script will pick up the CVSROOT from the CVS/Root file. If you wish
-# to use a different CVSROOT, you must set CVSROOT in your environment:
-#
-#   export CVSROOT=:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot
-#   export CVSROOT=:pserver:username%somedomain.org@cvs.mozilla.org:/cvsroot
-# 
-# You must specify which products/modules you wish to checkout, with
-#   MOZ_CO_PROJECT, MOZ_CO_MODULE, and BUILD_MODULES variables.
-#
-#   MOZ_CO_PROJECT possibilities include the following:
-#     suite (Seamonkey suite)
-#     browser (aka Firefox)
-#     mail (aka Thunderbird)
-#     minimo (small browser for devices)
-#     composer (standalone composer, aka NVU)
-#     calendar (aka Sunbird, use this to build the calendar extensions also)
-#     xulrunner
-#     macbrowser (aka Camino)
-#
-# Other common MOZ_CO_MODULE options include the following:
-#   mozilla/other-licenses/libart_lgpl
-#   mozilla/other-licenses/bsdiff
-#   mozilla/tools/codesighs
-#
-# Other targets (gmake -f client.mk [targets...]),
-#    checkout
-#    build
-#    clean (realclean is now the same as clean)
-#    distclean
-#
-# See http://www.mozilla.org/build/ 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
-#   MOZ_CVS_FLAGS        - Flags to pass cvs (default: -q -z3)
-#   MOZ_CO_FLAGS         - Flags to pass after 'cvs co' (default: -P)
-#   MOZ_MAKE_FLAGS       - Flags to pass to $(MAKE)
-#   MOZ_CO_LOCALES       - localizations to pull (MOZ_CO_LOCALES="de-DE,pt-BR")
-#   MOZ_LOCALE_DIRS      - directories which contain localizations
-#   LOCALES_CVSROOT      - CVSROOT to use to pull localizations
