Perhaps this is OT, but since command line parsing is part of configuration, I figure I'd throw it out there. My scripts often have configuration that the command line can override and I loosely follow the example hierarchy[0] listed in The Art of Unix Programming.

Some configuration I want in a config file (but I want to override from the command line) and sometimes it's very nice to use environment variables for configuration.

The idea was discussed in the list many years ago but it seems to be forgotten now.

Does anyone else have interest in such functionality? Is it outside the realm of this PEP?

It is outside the scope of this particular PEP, but it is certainly an interesting idea. Actually it is the Right Thing, but I doubt it is possible to implement such a generic configuration framework in the Python standard library. Applications use different configfile layouts, some programs use w32 registry instead of configfiles...

       Programmers don't die, they just GOSUB without RETURN.
