# Slackware SlackBuild script 
# ===========================
# By:          Eric Hameleers <alien@slackware.com>
# For:         mirall
# Descr:       desktop syncing client for OwnCloud
# URL:         http://owncloud.org/
# Needs:       qtkeychain
# Changelog:   
# 1.1.0-1:     13/Oct/2012 by Eric Hameleers <alien@slackware.com>
#              * Initial build.
# 1.2.5-1:     25/apr/2013 by Eric Hameleers <alien@slackware.com>
#              * New release, accompanying ocsync-0.70.7.
# 1.4.2-1:     03/dec/2013 by Eric Hameleers <alien@slackware.com>
#              * Update, accompanying ocsync-0.90.4.
# 1.5.1-1:     14/feb/2014 by Eric Hameleers <alien@slackware.com>
#              * Update, accompanying ocsync-0.91.4.
# 1.5.4-1:     07/may/2014 by Eric Hameleers <alien@slackware.com>
#              * Update, Ocsync now included in the mirall source, therefore
#                no longer an external dependency. The qtkeychain is still
#                a dependency for mirall.
#                Note: since mirall requires qt >= 4.8 this package can
#                      not be built on Slackware 13.37.
# 
# Run 'sh mirall.SlackBuild' to build a Slackware package.
# The package (.tgz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'.
