   Ahh, I think you tried the first one that Maurice posted.  I had a quick glance   
   at that source and noticed there was no file handling in it, and you've   
   confirmed my suspicions.   
      
   Try the second link Maurice posted.  For me, that one produces the same result   
   as the DOS CRC32.COM utility.  Now just have to tweak the output a bit, then   
   try hatching a file with that CRC value.  Running crc32 --help simply produces   
   an error message saying it can't find a file called "--help".    
      
    AI> I don't know if I compiled it right.. I simply did gcc crc32.c.   
      
   I did:   
      
   gcc -o crc32 crc32.c   
      
   Just to make sure I generated the binary with the name I wanted.   
      
   Anyway, next step is to tweak the source to produce the output I want (i.e.   
   easy to stuff into a .tic file without extra string manipulation), then try   
   hatching a file with a CRC value specified.   
      
   Stay tuned! :)
