Fix epub output (I had to steal makefile from admindocs!)

[symgryph]

Which Document page:

UserDoc page

Expected results:

Successful compile of the epub format

Actual results:

System complains of 'mconfig' being missing. Only way to fix was to copy the 'working' makefile from admin docs, and type

make epub

[symgryph]

Probably need to add the following to the readme:
git submodule init
git submodule update
make epub

[symgryph]

still get 'unknown command mconfig' after this. alas.

Good point, that should be in the README. Would you mind submitting a PR?

From a clean clone if I run those two submodule commands, apptainer_source/mconfig exists and imake epub successfully runs ./mconfig. I'm not sure what's happening in your environment. Perhaps you can provide some more details to reproduce.

Note that the README does say to use SKIPCLI=1 if you don't care about the CLI docs, and that if you don't set that you need the go environment set up. It just doesn't say to do git submodule init.
