# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        newt
# Descr:      semi-graphical interface development kit
# URL:        http://partimage.org/
# Needs:      
# Changelog:  
# 0.51.6-1:  07/Aug/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Initial build.
#              Newt provides a Python module. This module is built for my
#              current version of Python (you might need to recompile newt).
# 0.52.2-1:    26/Jan/2008 by Eric Hameleers <alien@slackware.com>
#             * Update. The sources are no longer downloadable from
#               partimage.org so we get them from debian.org
# 
# Run 'sh newt.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'. 
#
# -----------------------------------------------------------------------------
