But I want to feed it .lyx, or .txt, or .someproprietaryformat...
using .anythingspecific implies the file is an anythingspecific file,
and I will need a new tool to convert from .mything to
.anythingspecific.  e.g., It is trivial to arrange for a .lyx to have
an additional comment in its preamble, and everything would just work
without any tools aside from the actual filter|process needed to get
at the code.
