Sortpro is a PlugIn for Notepad from Mark D Esposito,
which sorts your Notepad items by project completion date and
within every date by priority.
For every completion date found Sortpro includes a line like 
this: 

     -> *** 04.06.1993 
or
     -> *** Jun,04 1993
for non german OS systems.

if there is a completion date and 

     -> *** General 

if the item don't has a project completion date. 

Don't worry about the priority 9 for this date-lines .
In reality it's the inexistent priority 0. I had to do this to
guarantee that this item becomes the first for the date. 

I wrote Sortpro as a feature of a new version for Diary, but I believe 
that it me be interesting for other users also. 

Let me know any troubles you have.
