# This needs CVSROOT set to work, e.g.
# setenv CVSROOT :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot

# setenv CVSROOT :pserver:username%somedomain.org@cvs.mozilla.org:/cvsroot
# 
# Usage:
# Pull the source:
#   cvs checkout mozilla/client.mk
#   gmake -f mozilla/client.mk checkout
#
# Build NSPR, maybe only once:
#   gmake -f mozilla/client.mk nspr
#
# Build the client:
#   gmake -f mozilla/client.mk build
#
# see http://www.mozilla.org/unix/ for more information

# MOZ_TOOLKIT		 - toolkit for configure --enable-toolkit=
