# 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).
#
# Run 'sh SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
#
# -----------------------------------------------------------------------------
# --- INIT ---
# Set initial variables:
