GPSBabel Behavior Directives
There are a few available directives to control some of the internal 
processing functions of GPSbabel.
   This sets the maximum allowed shortname length when using the internal
   shortname synthesizer.
   example:
   SHORTLEN	16	# shortnames will be at most 16 characters long.
   This tells the shortname synthesizer whether or not to allow whitespace
   in the synthesized shortnames.  Allowed values are zero and one.
   example:
   SHORTWHITE	0	# Do not allow whitespace in shortname.
   SHORTWHITE   1	# Allow whitespace in shortname.
