I think I would disagree. I spent some time time reading through the glue
code trying to figure out exactly what was going on and I found it
helpful. A lot of the shell_minimal.html isn't really necessary, but you
do need a good chunk of that "Module" javascript code, and the {{ SCRIPT }}
tag (like you said).
Anyway, it really isn't all that complicated. I was just wondering if
there was any documentation, which it sounds like there really isn't. At
the moment it looks like you just have to read through the code and figure
out what is going on, which wasn't as difficult as I thought it might be.
Thanks for getting back to me.
