# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        truecrypt
# Descr:      On-the-fly disk encryption
# URL:        http://truecrypt.org
# Needs:      
# Changelog:  
# 4.0-1:     02/Nov/2005 by Eric Hameleers <alien@slackware.com>
#            * Initial build.
# 4.2-1:     18/apr/2006 by Eric Hameleers <alien@slackware.com>
#            * This release makes the Linux build independent of MS Windows.
#              (so far, crypted containers could only be created in Windows).
# 4.2a-1:    03/oct/2006 by Eric Hameleers <alien@slackware.com>
#            * Bugfix update. Reworked the SlackBuild too.
# 4.2a-2:    14/jan/2007 by Eric Hameleers <alien@slackware.com>
#            * Fix compilation under kernels 2.6.18 and 2.6.19.
# 4.3-1:     15/apr/2007 by Eric Hameleers <alien@slackware.com>
#            * Update.
# 4.3a-1:    26/may/2007 by Eric Hameleers <alien@slackware.com>
#            * Update. This fixes a security issue with seteuid.
# 4.3a-2:    26/may/2007 by Eric Hameleers <alien@slackware.com>
#            * Device-mapper is part of a Slackware 12 install, so don't
#              list it as a dependency.
# 4.3a-3:    13/oct/2007 by Eric Hameleers <alien@slackware.com>
#            * Add patch to support kernel >= 2.6.23
# 5.1a-1:    04/Jul/2008 by Eric Hameleers <alien@slackware.com>
#            * New release requires wxWindows for the GUI, no longer is
#              kernel version dependant (by using fuse). 
# 6.0a-1:    10/Jul/2008 by Eric Hameleers <alien@slackware.com>
#            * New release
# 6.2a-1:    06/sep/2009 by Eric Hameleers <alien@slackware.com>
#            * New release
# 6.3-1:     27/oct/2009 by Eric Hameleers <alien@slackware.com>
#            * New release. Since we do not ship nautilus, use xdg-open.
# 6.3-2:     27/oct/2009 by Eric Hameleers <alien@slackware.com>
#            * Updated the "open container directory" patch to get rid of
#              a (harmless) error message.
# 6.3a-1:    04/apr/2010 by Eric Hameleers <alien@slackware.com>
#            * New release.
# 6.3a-2:    31/may/2010 by Eric Hameleers <alien@slackware.com>
#            * Rebuilt for Slackware 13.1.
# 7.0-1:     21/jul/2010 by Eric Hameleers <alien@slackware.com>
#            * Update to 7.0.
# 7.0a-1:    15/may/2011 by Eric Hameleers <alien@slackware.com>
#            * Update to 7.0a.

# 7.1a-2:    31/mar/2012 by Eric Hameleers <alien@slackware.com>
#            * I had forgotten to update the two patches for umount and diropen.
