On a Unix system, it may be, that file name extensions
are used to a great degree in order to distinguish file
types to the user, but the inverse ratio of *programs*
actually use the extension to decide the type. They
either use the first four bytes of the file, look at
command line options, or just
trust that the user gave the proper data type. In this
sense, I don't think that examining a file extension (or
any part of it's name) is 'ordinary' to Unix, although
it has been chosen from time to time (gzip and others).
I think that you have a fine point about the syntax
however, and I would not want to change the usage of
ecasound in a way that would affect people using it
now. I agree that it should be some optional add on
argument. Yeah, why not at the end of the -f bit?
