# Slackware SlackBuild script 
# ===========================
# By:          Eric Hameleers <alien@slackware.com>
# For:         mozilla-firefox-l10n
# Descr:       Mozilla Firefox localization
# URL:         http://mozilla.org/
# Needs:       
# Changelog:   
# 15.0.1-1:    07/Sep/2012 by Eric Hameleers <alien@slackware.com>
#              * Initial build.
# 21.0-1:      22/may/2013 by Eric Hameleers <alien@slackware.com>
#              * Update required because since version 21, the global extensions
#                are installed into a new directory. Also, it is not needed to
#                extract the xpi file (thanks Tomek).
# 
# Run 'sh mozilla-firefox-l10n.SlackBuild' to build a Slackware package.
# The package (.txz) and .txt file as well as build logs are created in /tmp .
# Install it using 'upgradepkg --install-new'.
