Routines prefixed with 'lpx' are old api routines (introduced about
5 yrs ago). Eventually they will be replaced by new, improved api
routines prefixed with 'glp'. However, all the old api routines, which
are _documented_ (starting from version 4.0), will be also available
for backward compatibility.

You can use both 'lpx' and 'glp' versions of the same routine, though
it is recommended to use the new, 'glp' version.
