# Slackware build script for ded

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# At one time, there was a ded package on slackbuilds.org, for Slack 12.2.
# This build script was written from scratch for 14.1, without referring
# to the old script.

# 20170819 bkw:
# - ftp server's been down >1 week, use http archives for DOWNLOAD

# 20170305 bkw:
# - stop gnulib's long filename test from writing to /usr/lib and /var/lib

# 20150909 bkw:
# - updated for 20150704 release

# 20140826 bkw:
# - updated for 20140722 release
# - added td_lib docs in /usr/doc
