# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       ipw3945
# Descr:     Intel PRO/Wireless 3945ABG Driver for Linux
# URL:       http://ipw3945.sourceforge.net/
# Needs:     Linux kernel >= 2.6.13
# Changelog:
# 1.2.0-1:   07/Feb/2007 by Eric Hameleers <alien@slackware.com>
#            * Initial build, based on Yalla-one's SBo script.
# 
# Run 'sh ipw3945.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
