If you seen the Ads for VEDIT and noticed the multi-file windowing claims
you may have wondered what good is it!  Shown below are several different
window configurations.  The first one shows how it can be used to compare
files.  In the example are two revisions of a MEX overlay.  

VEDIT has a lot of other nice features:

- extensive macro (script file) capability
- keyboard macros
- small size
- fast loading
- comprehensive install program with COMPLETE keyboard redefinition.

and more.
