# Needs:      
# Changelog:  
# 0.3.8.1-1:  17/Dec/2008 by Eric Hameleers <alien@slackware.com>
#             * Initial build.
# 0.3.8.1-2:  13/may/2009 by Eric Hameleers <alien@slackware.com>
#             * Rebuilt for python 2.6.2.
# 
# Run 'sh recordmydesktop.SlackBuild --cleanup' to build a Slackware package.
# The package (.txz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'.
