# 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 new tree,
#    1. cvs co mozilla/client.mk
#    2. cd mozilla
#    3. gmake -f client.mk webconfig
#       (or goto http://cvs-mirror.mozilla.org/webtools/build/config.cgi)
#    4. gmake -f client.mk
#
# To checkout (update) and build an existing tree,
#    gmake -f client.mk
#
# Other targets (gmake -f client.mk [targets...]),
#    checkout  (also pull_all)
#    build     (also build_all)
#    realclean (also clobber_all)
#    clean     (also clobber)
#
# The nspr library is handled as follows,
#    Read $HOME/.mozmyconfig.sh (or $(TOPSRCDIR)/myconfig.sh) and
#    get the directory specified by --with-nspr.
#    If the flag is not there, look for nspr in /usr/bin.
#    Otherwise, build from tip and install in $(OBJDIR)/dist/nspr
#
# See http://www.mozilla.org/build/unix.html for more information.
#
# Options:
#   MOZ_WITH_NSPR       - Nspr directory for configure --with-nspr=
#   MOZ_WITH_PTHREADS   - Pthreads for nspr and configure
#   MOZ_OBJDIR          - Destination object directory
# also,
#   MOZ_CO_BRANCH       - Branch tag to use for checkout (default: HEAD)
#   MOZ_CO_MODULE       - Module to checkout (default: SeaMonkeyEditor)
#   MOZ_CVS_FLAGS       - Flags to pass cvs (default: -q -z3)
#   MOZ_CO_FLAGS        - Flags to pass after 'cvs co' (default: -P)
