Here at SR, we have many signal processing programs which are able to
contort signals into just about any new format.  We have adopted "."
suffixes (which can be supplied on the command line) to help organize 
this mess.

The big problem occurs when you try to do > 1 extension.  Our solution
was to write an add_extension(fname, extension) function.  If extension is
not empty (or not NULL), fname is truncated after the last '.' and extension
is appended.  It works very nicely.
