NUKE
Revision history:
1.00   -   initial release
1.01   -   changed incorrect filename (killdir) to NUKE in batchfile
1.10   -   changed .EXE file to use direct screen writes so messages can be
           seen even when output is redirected to NUL. Also added SAFFENUKE
           program to give the user a chance to change their mind. SAFENUKE
           wants a "yes" to proceed; "y" will not do. If you do not want to
           see any messages (except the unavoidable "file not found" when you
           delete an empty subdir - I can fix this, if it really bothers anyone)
           get NUKE v2.0A.
2.0/2.0A - Rewrote alot of code, v2 is slightly smaller & faster (less
           convoluted) - I realized that there were major quirks/bugs in v1.1;
           sorry, I think they have all been fixed. v2.0 will write msgs to the
           screen even when output is redirected; v2.0A will not write to the
           screen when output is redirected.
