# For:       xerces-c
# Descr:     a validating XML parser
# URL:       http://xml.apache.org/xerces-c/
# Needs:     
# Changelog:
# 2.7.0-1:   21/Jan/2007 by Eric Hameleers <alien@slackware.com>
#            * Initial build.
# 2.8.0-1:   09/Jan/2008 by Eric Hameleers <alien@slackware.com>
#            * Initial build.

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