-- THESE FUNCTIONS ^^^ ARE NOT IMPLEMENTED FOR THE ADA BINDING
-- EXCEPT FOR THE FOLLOWING.
-- This procedure is currently GNAT-specific, importing Gnat_Argc and Gnat_Argv.
-- Process options list using current options info.

-- fix this These functions are redundant with those in plplot_thin.
-- This might be OK since they are now available at all levels of binding.
-- I wonder if this is approaching "wrapper bloat" since these procedures
-- get called a lot of times during the making of a contour plot.
-- The way to eliminate one level of calling would be to move the bodies
-- of pltr? from plplot_thin.adb into plplot_traditional.adb and
-- plplot.adb, then optionally eliminating the bodies from plplot_thin.adb
-- on the idea that nobody is going to use them anyway. But even if the
-- bodies were left in plplot_thin.adb, having them here would still
-- remove the extra call level. The argument for the current arrangement is
-- easier code maintainence.
-- Identity transformation.
