Bug 107188 – Reorganize webkitdirs.pm into modular pieces

• Status: ASSIGNED
• Component: Tools / Tests

[David Farler]

webkitdirs.pm is currently too state-oriented and overloaded in functionality to easily extend. I propose the following:

- Separate ports and extend a common interface
- Separate the concerns of command line options, utility functions, etc.
- Recommend rewrite in something like Python
- Automatically generate usage help using something like argparse
- Reduce reliance on state
- *Do not* mutate ARGV

For command line options:
- dynamically add argument sub-parsers depending on the tool and port

For utility functions:
- separate the various ports to ease merging and preventing interference

All of this might entail refactoring a lot of the tools but I think the long-term benefit would be worth it. Being able to centralize library behavior so that all ports can extend or utilize modules without interfering with each other would be a good thing.
