Routine Desscription:

This routine parses the command line parameters, maps the GPC file into memory
and creates the output GPD file. It then starts converting GPC data by calling
various sub-routines. If any error occurs, it reports errors and tries to
continue if possible.

The following command line parameters are supported:
    -I<GPC_file> : the file name does not need double quotes. Ex. -Icanon330.gpc
    -M<model_id>: an integer, such as 1, which is the string resource id of the
                  the model name in the .rc file that comes with the given GPC
                  file.
    -N<model_name>: a string, such as "HP LaserJet 4L".
    -R<resource_dll>: the resource dll to be associated with the generated GPD
                      file. Ex. -Rcanon330.dll
    -O<GPD_file>: the output GPD file name. Ex. -Ohplj4l.gpd
    -S<style>: the string style used in generating the GPD file for standard names.
               -S0 means using the direct strings for *Name entries.
               -S1 means using string value macros for *Name entries. This is
                   mainly used for on-the-fly conversion. The value macros are
                   defined in printer5\inc\stdnames.gpd.
               -S2 means using RC string id's. These strings are defined in
                   printer5\inc\common.rc.
    -P         rcNameID: 0x7fffffff  for standard papersizes.

Arguments:
        argc - number of arguments
        **argv - pointer to an array of strings

Return value:
        0
