# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       truecrypt
# URL:       http://www.truecrypt.org/
# Needs:     device-mapper >= 1.00.08
# 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:       15/apr/2007 by Eric Hameleers <alien@slackware.com>
#            * Update.
# 
# Run 'sh SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
