6 Functions to parse and format bearing, compass, lat- and longitudes in various forms of

7 degrees, minutes and seconds with or without degrees, minute and second symbols plus a

8 compass point suffix, including parsing of C{decimal} and C{sexagecimal} degrees.

9

10 Set env variable C{PYGEODESY_FMT_FORM} to any C{F_...} form to override default C{F_DMS}

11 formatting of lat- and longitudes or to an empty string to restore the default.
