Stefan and Paul,
I added Paul's HOWTO on the Open File Wizard to the OpenJUMP Wiki
under the documentation/developer section.
There may be a way to make the code look a little nicer with the wiki
formatting. When I first pasted the text in it was doing some wierd
things with scrolling windows. I got rid of these, but the code
doesn't look great without the spacing and/or tabs.
Stefan can let me know if I got this in the correct spot on the wiki,
or if he had another place in mind.
