    I am doing the following:
    # diff file(new) file(old) > file.patch
    Is this correct?
    Is it possible to make one patch for several files?

      (This really isn't anything to do with GPSim, but I'll answer anyway)

      You need to give diff some option arguments to get a meaningful patch format. From memory I think the -c option (or -Cx where x is the number of lines) gives the right "context" format, or -u for the "unified" format. You also need to ensure the files are in the right order, namely old then new.

      If you want to create a patch from multiple files, the do a diff of the directory structures. For that you will need the -r (recurse) option, and probably -N to treat "new" files as if the missing one were just empty.

      You may want to look at http://www.cpqlinux.com/patch.html

      Or you could have typed "patch file using diff" into google, like I did.
