Subject: [PATCH] website-build: serve.sh: help: fix program name.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The GNU Coding Standards has the following in the chapter "4.8.1
--version"[1]:
    The program’s name should be a constant string; don’t compute it
    from argv[0]. The idea is to state the standard or canonical name
    for the program, not its file name. There are other ways to find
    out the precise file name where a command is found in PATH.

This fixes that.
