This is a freeware program to delete all the zero-length files in a
directory that match a wild card specification.

Usage syntax is:

DELZERO [d:][\path\]wild_card_spec

For example DELZERO *.* will erase all zero-length files in the current
directory.  DELZERO c:\fd\*.out will erase all zero-length files in 
C:\FD with the extension OUT.

If a wild card is not given, the program will halt with a help screen
and an errorlevel or 255.
