We added XrefIT, a cross reference system and natural complement to ChangefIT to our product list in mid-2009.
The original X-Cmd utility was written as an in-house utility a number of years ago. XrefIT v1.21 was the first release of this utility and, as such, contains a number of upgrades it should cater for many of your cross-referencing needs. Naturally we will continue further development of XrefIT in the future to cater for technological advances made since X-Cmd was originally written as well as adding further functionality.
If you would like more information about XrefIT, access to our XrefIT wiki is available 24/7. Registration is required at our support portal.
