%s Usage:
%s [options] vssProject descFile stampPath

Automatically brand a VSS project with an automatically incremented
build number, and stamp DLL/EXE files with the build number.

Checks that no files are checked out in the project, and finds the last
build number, and suggests the next number.

Options:
-a     - Auto increment the build number, and brand (otherwise prompt
         for the build number after looking for the previous)
-r     - Restamp the files with the existing build number.
-d     - A description for the VSS Label.
-f infile=outfile - Substitute special VSS labels in the specified text
                    file with the text extracted from VSS.
