# 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
# 
# Usage:
#
#  To checkout and build a new tree,
#      cvs checkout mozilla/client.mk
#      gmake -f mozilla/client.mk
#  To checkout (update) and build an existing tree,
#      gmake -f mozilla/client.mk
#  To only checkout, configure, or build,
#      gmake -f mozilla/client.mk [checkout] [configure] [build]
#
# See http://www.mozilla.org/unix/ for more information.
#
# Options:
#   NSPR_INSTALL_DIR     - nspr directory for configure --with-nspr=
#   USE_PTHREADS         - pthreads for nspr and configure
#   MOZ_OBJDIR           - destination Object Directory (relative path)
# also,
#   MOZ_CVS_FLAGS        - flags to pass to CVS
#   MOZ_CHECKOUT_FLAGS   - flags to pass after cvs co
#   MOZ_BRANCH           - default branch to checkout
#   MOZ_TOOLKIT          - toolkit for configure --enable-toolkit=
