# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        amaya
# Descr:      web authoring environment
# URL:        http://www.w3.org/Amaya
# Needs:      
# Changelog:  
# 11.2-1:     26/Jul/2009 by Eric Hameleers <alien@slackware.com>
#             * Initial build.
# 
# Run 'sh amaya.SlackBuild' to build a Slackware package.
# The package (.tgz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'. 
#
# -----------------------------------------------------------------------------

TAG=${TAG:-alien}

# Where do we look for sources?

# Place to build (TMP) package (PKG) and output (OUTPUT) the program:
TMP=${TMP:-/tmp/build}
PKG=$TMP/package-$PRGNAM
OUTPUT=${OUTPUT:-/tmp}
