name of the program, which might be quite long. 

maybe, in a not so elegant fashion, this would do a decent job:

char *last_sep = strrchr(argv[0], '/');
if (last_sep && last_sep[0]) 
   last_sep++; /* skip past the slash */
 else
   last_sep=argv[0]; /* it wasn't the whole path */

fprintf(stderr,"Usage: %s [inputBase] [outputFile]\n", last_sep);

Of course that can be compacted a lot....
