suggestions for freesbie2

I am looking at the code to understand how it works, and I have a few
suggestions:

1 each file under extra (and maybe also under scripts) should have
  a line like:
  DESC="short description of what this plugin does"
  this would allow:
  1. to know what the plugin does ;-)
  2. to generate automatically a web page (or whatever format) with
     the description of each plugin. This would allow to have the
     documentation updated automatically

2 refactor common code.
  a lot of files have the same blurb:
if [ -z "${LOGFILE:-}" ]; then
    echo "This script can't run standalone."
    echo "Please use launch.sh to execute it."
    exit 1
fi

  this should go in a new file as a function, say common.sh, 
  and the existing files should source common.sh

3 I have the feeling that img.sh and flash.sh have a lot in
  common. They should be refactored to exploit the commonality.


I think I can do some of this, if we agree on the direction.
