[Gzz] make copyrighted

[B. Fallenstein]

Hiya,

Here's a cute little tool. When creating a new file, instead of copying 
another file's header, you can now just start it like this:

    //(c):Benja Fallenstein
    package gzz.impl;
    import gzz.*;

    /** Just one of 'em classes... */
    public class Foo {

Or, in Python and similar,

    #(c):Benja Fallenstein
    """
    foopackage.py-- What a wonderful package!
    """

After creating one or more of these, before committing, you do

    make copyrighted

and that walks the whole tree (takes a while), looking for files 
starting with one of the magical strings ('#(c):' and '//(c):') and 
creates the appropriate headers (filename, copyright, license statement, 
written by). It even takes the year from your system time, so you can 
safely continue using it in 2003 ;-)

Plus points:
- Less work.
- You write the import statements yourself, thus don't copy superfluous 
lines.
- Never forget any changes in the headers.
- Now the headers can go even into .pys and .tests-- they belong in 
*all* files.

Makin' life a lil' easier,
- Benja
