[Gpsbabel-misc] autodetect input format?

[Vidar G. <vid...@37...>]

would an "-i autodetect" option (which also would be default)
be technically possible with gpsbabel?

lets say i want to autoprocess a lot of GPS logs from
different GPS units, is there a front end available to
send the appropriate input format to GPSBabel? do most GPS
receiver logs have their own file extension, so that the
file extension can be used in a LUT and sent to the -i
option?

anyone on this list done anything similar to this?
