Generated ePubs failing validation

[Hasimir]

Hello,

Following on from my latest pull request (#412) here are all the ePub validation failures from trying to export the guide.

That pull request should fix the first three errors. The eleven after it appear to be due to those pages having the quick search widget on them and the start button for it. The next two, along with the two at the end, are broken identifiers in the TOC (probably best to leave these until last). The last error is simply a case of an image being called from another server, but ePub needs all those objects. Fixing this last one just means uploading http://www.python.org/dev/peps/pep-0001/pep-0001-1.png to a suitable location and updating intro/community.rst to use the local version.

@kennethreitz what has been the guide's position on ePub versions? I've never seen any advertisement that they're generated.

[Hasimir]

Well, there was existing config parameters listing @kennethreitz as the publisher, so it might've been intended at some stage and all those a fixable (the ones with little search widgets might require a little more work, depending on what options sphinx provides for culling scripts during the conversion process).

[sigmavirus24]

@Hasimir just because something is there does not mean it is intentional, especially when dealing with Sphinx. Sphinx will auto-generate much of the configuration for you based on a few prompts and I would hazard a guess that this is one of those instances where Sphinx built all of this for us without it being intended to be used as an ePub.

[Hasimir]

Could be ... take a vote on it or something. If you decide against ePub I'll go find the bit of code you'd need to remove (or comment out with a bunch of warnings that it's not supported and people can use it at their peril) to explicitly prevent an ePub being made from it without manual intervention by a determined end user.
