xbard feature request

Hi. I am a happy user of xboard and I would like to suggest a new feature. It would be fantastic in the program could take a multigame pgn file and analyze all the games within it, in the same way the 'annotate' crafty function does. In this program, user inputs a request like this:

annotate <file> <color> <moves> <margin> <time> [nmoves]

It would be great  if this new feature could work also from the command line, without having to load the GUI.

Please, let me know if you need more details about this feature request.

Thanks for your consideration.

Giovanni
