## REMOVE THIS ENTIRE BLOCK OF TEXT (AFTER READING IT!)

## This template is not meant to be a "cut and paste" script to enable
## any random user to make a working package.  While we're certainly not
## discouraging use of this template, if you haven't manually gone
## through each step of the process without the build script (typically
## as a normal user, as this will reveal problems that you won't see as
## root), then there's a good chance that something important is missing
## from your submission.
##
## When using this template script, please remove as many of these
## unnecessary comments as possible.  Commented code is a good thing, but
## if it's obvious, there's no need to comment it.
## 
## AGAIN, REMOVE THE COMMENTS IF THEY ARE NOT NEEDED--DON'T JUST DELETE
## THIS BLOCK OF TEXT WITHOUT BOTHERING TO READ WHAT'S IN IT.
