# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       mcabber
# URL:       http://www.lilotux.net/~mikael/mcabber/
# Needs:     openssl, ncurses, gpgme
# Changelog:
# 0.6.5-1:   17/Aug/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Initial build.
# 0.6.6-1:   18/Aug/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * New release
# 0.7.3-1:   13/jan/2006 by Eric Hameleers <alien@slackware.com>
#            * New release
# 0.7.4-1:   18/jan/2006 by Eric Hameleers <alien@slackware.com>
#            * Bugfix release. Mention MUC capability in slack-desc.
# 0.7.5-1:   04/apr/2006 by Eric Hameleers <alien@slackware.com>
#            * New release.
# 0.7.6-1:   19/apr/2006 by Eric Hameleers <alien@slackware.com>
#            * Bugfix release.
# 0.7.8-1:   28/jun/2006 by Eric Hameleers <alien@slackware.com>
#            * New release. 
# 0.8.0-1:   14/aug/2006 by Eric Hameleers <alien@slackware.com>
#            * New release. Small ncurses detection fix needed. Mcabber will
#              now by default check the server's SSL certificate - to disable
#              that, add "ssl_verify = disable" to your mcabberrc.
# 0.8.1-1:   23/aug/2006 by Eric Hameleers <alien@slackware.com>
#            * New release (configure bugfix).
# 0.8.2-1:   19/sep/2006 by Eric Hameleers <alien@slackware.com>
#            * New release.
# 0.8.3-1:   19/nov/2006 by Eric Hameleers <alien@slackware.com>
#            * New release. Lots of new features, read the changelog.
# 0.9.0-1:   16/dec/2006 by Eric Hameleers <alien@slackware.com>
#            * New release. PGP encryption supported. Updated the SlackBuild.
#              Note: if you don't have "gpgme" installed, then mcabber will
#                    automatically build without PGP support.
# 0.9.1-1:   10/feb/2007 by Eric Hameleers <alien@slackware.com>
#            * New release. Removed that GPL clause in this script's header.
# 0.9.2-1:   12/jun/2007 by Eric Hameleers <alien@slackware.com>
#            * New release.
# 
# Run 'sh mcabber.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
