# This is not a source build script.  Rather, it builds a Slackware
# package from the official binary tarball available from mozilla.org.
# Using the official binaries seems like the most direct way to satify
# the Mozilla project's concerns about quality control (and thus to
# provide the most quality-certified package possible), and therefore
# be able to use the official trademarks and logos.
#
# Thanks to the folks at the Mozilla Foundation for permission to
# distribute this, and for all the great work!  :-)
