+**  STUB.C - Utility to truncate files
+**
+**      STUB is used with MAKE utilities which lack the ability to timestamp
+**      library object modules to reduce disk space requirements. After
+**      compiling and building your library or executable, run "STUB *.OBJ"
+**      to truncate all object files to zero length. The files' time and
+**      date stamps will remain unchanged. By doing this, your make utility
+**      will still know which modules are out of date even though the files
+**      themselves have all been truncated to zero length. STUB also supports
+**      the standard response file format so you can use your linker response
+**      files to direct the files to be truncated.
+**
+**  public domain by Bob Stout
+**
+**  Notes: To expand command line arguments with wildcards,
+**         TC/TC++/BC++  - Link in WILDARGS.OBJ.
+**         MSC/QC        - Link in SETARGV.OBJ.
+**         ZTC/C++       - Link in _MAINx.OBJ, where 'x' is the memory model.
+**         Watcom C/C++  - Compile & link with WILDARGV.C
+**
+**         Allows file list(s) using standard "@file_list_name" convention.
