[LON-CAPA-users] tex in loncapa

[lon-capa-users@mail.lon-capa.org]

This topic leads me to wonder what people see as best practice when
publishing larger documents (which may require frequent revision), for both
web and prt outcomes.  If one already has such a document in TeX, one might
still want to produce a redundant html version with snippets inside <m></m>?
 Or, would it be more practical to simply maintain the entire document
outside of loncapa and produce pdfs to be uploaded and published as such?

Other options... (with a view to best compromise between quality of results
for both web and print, and ease of maintenance)?
