You can find out the version by typing "version" at the gempak prompt
of a program (such a gdprof).

Use gdprof for a skew-t from a gridded file (or you can use Garp or nsharp).
In gdprof, type "phelp gdprof" for online help.

You will need to run gdprof twice for a traditional skew-t plot.
Run once for GFUNC=tmpc, CLEAR=yes to plot the temperature profile.
The second time, use GFUNC=dwpc, CLEAR=no to overlay the dewpoint profile.

Set GPOINT to the station id or lat;lon you want the profile for.

See the online help for the other variables of gdprof.
