# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       wpa_supplicant
# Descr:     WPA/WPA2/IEEE 802.1X Supplicant
# URL:       http://hostap.epitest.fi/wpa_supplicant/
# Needs:     Source code for supported wireless card drivers
#            openssl >= 0.9.7
# Changelog:
# 20040923CVS-1: * 23/sep/2004 by Eric Hameleers
#                First release.
# 0.3.8-1:       * 09/apr/2005 by Eric Hameleers
#                Update
# 0.3.8-2:       * 09/apr/2005 by Eric Hameleers
#                Enabled support for ndiswrapper.
#                Parametrized the location for the madwifi driver sources.
# 20050415-1:    * 15/apr/2005 by Eric Hameleers
#                Switched from 'stable' to 'development'.
#                The development branch has support for the 'any' ESSID, needed
#                to connect to 'any open' WiFi network (think: hotel/airport).
# 20050806-1:    * 06/aug/2005 by Eric Hameleers
#                This snapshot uses a madwifi-20050707 snapshot.
#                Make snapshot version visible in the program output.
# 20050809-1:    * 09/aug/2005 by Eric Hameleers
#                New snapshot, uses a madwifi-20050809 snapshot for testing
#                reportedly, tha last madwifi CVS snapshot to work with new
#                wpa_supplicant snapshots is 20050707.
# 20050913-1:    * 13/sep/2005 by Eric Hameleers
#                New snapshot from hostap cvs. Also, make the docs.
# 20051005-1:    * 05/oct/2005 by Eric Hameleers
#                New snapshot from hostap cvs, to test against today's madwifi
#                snapshot.
# 20051007-1:    * 07/oct/2005 by Eric Hameleers
#                New snapshot from hostap cvs, to test against today's madwifi.
#                This time, also incorporate a patch found here:
#                http://hostap.epitest.fi/bugz/show_bug.cgi?id=63 , which should
#                make madwifi/WPA work again.
# 20051008-1:    * 08/oct/2005 by Eric Hameleers
#                Looks like the patch made it into CVS! We can remove out patch.
# 20051014-1:    * 14/oct/2005 by Eric Hameleers
#                Update.
# 0.4.7-1:       * 31/jan/2006 by Eric Hameleers <alien@slackware.com>
#                Try a "stable" version for the madwifi-ng (Atheros driver) code
#                Also, get rid of the developer docs.
# 0.4.8-1:       * 17/feb/2006 by Eric Hameleers <alien@slackware.com>
#                Upgrade. This SlackBuild will now by default delete the
#                remainders of a previous compile in /tmp/tmp-$PRGNAM/.
# 0.4.9-1:       * 31/may/2006 by Eric Hameleers <alien@slackware.com>
#                Upgrade. This time, build the wpa_gui and man pages too.
#                Also, made support for madwifi/hermes/broadcom drivers
#                configurable using three *_INCLUDES variables.
# 0.4.9-2:       * 20/sep/2006 by Eric Hameleers <alien@slackware.com>
#                Changed the SlackBuild for Slackware 11.0 compatibility
# 0.5.7-1:       29/Jan/2007 by Eric Hameleers <alien@slackware.com>
#                * Update, remove GPL license.
# 
# Run 'sh wpa_supplicant.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
