I am unsure if there is some real use for this feature.
I'll append the most relevant message I found in my archives from 1995,
when the feature got added. In today's environment, I am not convinced.
I know that it is used for the metapost -> tex (resp. latex)
communication. But, is it useful for anything else in real life?
Why would it be needed for metapost->tex/latex? If there is *any* real
life application, then it's probably worth keeping.

For years, I've used a similar scheme. The only differences are that:
a) I use a separate 'wrapper' program instead of modifying virtex itself,
b) My wrapper looks for lines like: %format=latex
I have found that making all TeX files (regardless of what format they use)
self-identifying (so that 'tex some-file' is always sufficient to run them)
is very convenient. I strongly support getting functionality of this sort into
the standard distribution. Exactly what syntax to use is a minor detail --
I don't have any problem with Tom's choice. Whether to use a separate
wrapper program, or modify virtex itself, is an implementation detail.
I'd be happy to see the functionality in virtex itself.
