POD doc generator needs work

[mgage]

• The output of pod documents has been moved to
  https://demo.webwork.rochester.edu/wwdocs/
  (it can be reached from the webwork wiki author's page). It kind of works, but the script needs work to make the formatting better (e.g. including the parent directory).

• The newest code for the POD document generator: is in https://github.com/mgage/admintools/tree/master/pod_doc_tools and in the pull request: Added newer version of pod_doc_tools -- it still needs modifications … admintools#2

• The script is currently being hosted on demo.webwork.rochester.edu for the time being. It should be moved to a VM which is controlled by The WeBWorK Project.

Once there are generated POD files, they can apparently be hosted on GitHub.

See for example: https://github.com/openwebwork/pg/blob/master/doc/MathObjects/UsingMathObjects.pod

I recommend we consider whether the scripts could be set up to generate POD files and push them to a repo on GitHub instead of generating PDF files for hosting on some VM.

It could be that just the "table of contents" and/or "index" type pages need to be hosted outside GitHub, but probably if they were generated in markdown syntax - they could be on GitHub as .md files.
