# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       corefonts
# Descr:     TrueType core fonts for the web
# URL:       http://sourceforge.net/projects/corefonts/
# Needs:     (build time only:) cabextract
# Changelog:
# 1.0-1:     03/Nov/2007 by Eric Hameleers <alien@slackware.com>
#            * Initial build.
# 
# Run 'sh corefonts.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=corefonts
VERSION=${VERSION:-1.0}
ARCH=noarch
BUILD=${BUILD:-1}

# By using these fonts you agree to the following End User License Agreement:
DOCS="$SRCDIR/EULA.txt $SRCDIR/README.1st"

# 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:
TMP=${TMP:-/tmp/build}
PKG=$TMP/package-$PRGNAM
OUTPUT=${OUTPUT:-/tmp}

# The actual fonts we are going to package:
COREFONTS="andale32.exe webdin32.exe trebuc32.exe georgi32.exe verdan32.exe \
  comic32.exe arialb32.exe impact32.exe arial32.exe times32.exe courie32.exe"
