thanks for working on this.

Not sure we should really distinguish between mytex and mylatex. Any
use cases where both are needed as options?
Also, what exactly do we mean when we say "compilation route is
'latex' "? latex would produce a dvi file. Do we then convert it to
pdf, and if so how?
Also, should the user have a way of specifying that they want dvi
output instead of pdf output? Or do we somehow sniff that out of the

Actually those 1,2 are really one, using the options.sh/options.rb
script/library. There might be other files between the source file
and the master file, and those should be looked at as well. Also keep
in mind that there are multiple ways to define what the master file
is (I think options.sh/rb takes care of that).

This sounds reasonable. I would definitely want backwards compatibility.

Looks good overall.
