probably you can use gpsbabel for that.

it is best we outsource as much non-main-task stuff as possible to external
packages so we can focus out meager energy on what we do well, rather than
try to reinvent tangential wheels.

if some program has written a route to a GPX track, I think we can justify
asking the user to open the file as a GPX track, 'cause that's what it is
now.
