====== Slackware Buildscript Template ======

This is my version of a Slack Buildscript. I tried to separete the boilerplate code which stays the same in most buildscripts from the part which is really specific to the actual package. 

This script is based on the very good [[http://www.slackwiki.org/Writing_A_SlackBuild_Script|howto]] from rworkman. Howto use a buildscript for Slackware is described [[http://slackbuilds.org/howto/|here]].

# Provide a function wich copies the necessary docs to the doc directory:
# pwd is the sourcecode dir when this function is called

    # alternatively, if make install has already created 
    # a doc dir somwhere in the package tree:
