#21 Use "OPS" as the default subdir for holding EPUB content

[W. Eliot Kimber]

Apparently some EPUB readers expect the content to be in a subdir named "OPS", including the .opf and .ncx files. Make this directory structure the default.

Out of curiosity do you know which readers require this?

[W. Eliot Kimber]

The client couldn't name specific readers but thought they may have been Android readers. This is definitely not a requirement of EPUB but seems to be a side effect of sloppy reader implementation and/or misunderstanding of the EPUB spec.

Would making this the default be an issue for your EPUBs?

[Steven Calderwood]

Intriguing. I'm a bit surprised we haven't had complaints of that given all the different vendors we sell ours through. And no, this won't be an issue for ours. Thanks for asking.

[W. Eliot Kimber]

Hmm. Well it might be a non-issue, but the client is insisting on this organization.

[Steven Calderwood]

Understandable! Perhaps this should be controlled through a parameter like the images and topics output dir params? That might just be super overkill. (And again it doesn't bother me.)
