Ever wanted to be able to open a document in an X11 application by simply double-clicking it from the MacOS Finder? Well now you can!

By default XLaunch-O-Matic is able to open documents with

gv (.ps files)
gimp (.xpm files)
texmacs (.tm files)
lyx (.lyx files)
and more...

if they where installed by fink.

However you can map any document type to any application by simply double-clicking on the XLaunch-O-Matic icon and selecting preferences from the XLaunch-O-Matic menu.
