Place PHP documentation tree on GitHub Pages

[Xymph]

As proposed here, the documentation tree of the PHP code comments could be placed somewhere publicly, like on GitHub Pages. Here we can hash out the details.

Could this be done on https://xymph.github.io/ or is https://hamstar.github.io/ required because of repo ownership?

Which tool to use, which allows automation with GH Pages, which produces the nicest results?

• PHPDoc v2.9.1 or v3.0.0
• PHPDox
• ApiGen (already used by Requests)
• any others?

Plenty to research and experiment...
