Here's the sequence of events:

1. I wrote a test driver procedure for the Zoo package, named (quite creatively)
"Zoo_Driver."

2. I saved the procedure as Zoo_Driver.ads. This was a (minor) bad thing. GNAT
complained that I had saved a procedure body as a procedure spec, with the
humorous error message I posted originally.

3. I copied Zoo_Driver.ads to Zoo_Driver.adb. GNAT still complained that the .ads
file was misnamed (of course).

4. I tried to delete Zoo_Driver.ads.  No such function exists in WebAda.

5. I deleted the contents of Zoo_Driver.ads - made it a null file. GNAT complained
that it was a null file.

6. Finally, I put a specification for Zoo_Driver in Zoo_Driver.ads, namely:

   procedure Zoo_Driver;

and all was well. However, it's a little annoying - a delete function would have
been handy.

I'm not sure I see the difficulty. Currently, WebAda only shows me my files
on the file list. I can't edit other people's files, or pre-defined packages,
from that list. Just add a Delete button next to the Edit button on the file
list.
