# 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!  :-)

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|' on
# the right side marks the last column you can put a character in.  You must make
# exactly 11 lines for the formatting to be correct.  It's also customary to
# leave one space after the ':'.
