HEX to GC compressed

Does anyone have a program that preferably converts HEX to GC compressed or at least GC to GC compressed?  I'm using iConvert to go from HEX to GC, but wish they gave us the option of GC compressed.  GC, can you add that please?  I have a lot of HEX codes to convert and loathe the idea of converting to GC and then manually converting to GC compressed.

EDIT:

Here is a python program and a sample CSV file.  The commands generated should be correct, but I haven't tested it.  The program generates a CSV and XML document with all of the codes.  I don't do anything with the offset value, but from what I've read on here it's rare that it ever needs to be changed.

The csv file structure is:

Device name, connector address

Button name, repeat, hex code

hex.csv
buildxml.py

  Well, I wrote a small python program to convert the GC output of iConvert into GC compressed.  Still would be nice to not have to do two steps, but this works for now.  Can someone explain how you convert HEX to GC?

  I guess really the only part I haven't figured out is how you determine the frequency.  I assume it has something to do with the first four hex numbers, but I can't figure it out.  The ID is arbitrary and the rest if just straight conversion from hex to dec.

  Figured it out.  I found it here.  http://www.hifi-remote.com/infrared/IR-PWM.shtml

  1000000/(N * .241246) where N is the second hex number.  Once I get the code fully working I'll post it up.  That way if anyone needs to do batch conversion of hex to GCC can.

  Hi Mark and Matthew,

  The GC compressed format is described in our iTach API.  While currently iConvert does not have an option to convert codes to the compressed format, iLearn does.  To do this paste a command in the GC format into the edit view of iLearn, set the Save format to GC Compressed and press save data.  The command will show up in the results field in the GC compressed format.  Results can then be saved to their own file as a codeset or can be copied out of the results field individually.
