Q:Hi, I noticed that if you concat two (or more) xfms together with xfmconcat, that the command is not recorded in the xfm’s comments field. xfminvert for example records the history of how the xfm was created. I think this is an excellent feature so i played with the xfmconcat code a bit so that it recorded things properly (at least I think I am doing it properly).

The main change was
if (output_transform_file(argv[output_arg], NULL, new_result) != OK) { to
if (output_transform_file(argv[output_arg], arg_string, new_result) != OK) {

where arg_string is:
#include <time_stamp.h>

 char *arg_string;
 arg_string = time_stamp(argc, argv);

I would like to submit my new version to the cvs but I must admit that I have no idea how to do this or what standards I would need to follow. If someone can help me out that would be great, alternatively, the new code is attached.

A: Thanks for the patch, I have just added it to CVS. Expect to see it in MINC 2.0.15
