# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        qcad
# Descr:      a simple 2D CAD program
# URL:        http://www.qcad.org/qcad.html
# Needs:      
# Changelog:  
# 2.0.5.0-1:  06/Mar/2008 by Eric Hameleers <alien@slackware.com>
#             * Initial build. To be anything like useful, qcad needs a parts
#               library - we wrap that into a separate package.
# 
# Run 'sh qcad.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'. 
#
# -----------------------------------------------------------------------------

# Set initial variables:

PRGNAM=qcad
SRCVER=${SRCVER:-2.0.5.0-1}
VERSION=$(echo $SRCVER | tr '-' '_')
MANVER=${MANVER:-2.1.0.0-1}
PARTVER=${PARTVER:-2.1.2.8-1}
VERSION2=$(echo $PARTVER | tr '-' '_')
ARCH=${ARCH:-i486}
BUILD=${BUILD:-1}

DOCS="qcad/README qcad/data"

# Where do we look for sources?
CWD=$(pwd)
SRCDIR=$(dirname $0)
[ "${SRCDIR:0:1}" == "." ] && SRCDIR=${CWD}/${SRCDIR}

# Place to build (TMP) package (PKG) and output (OUTPUT) the program:
