                      5:

                      8: .SH DESCRIPTION
                      9: .I cvftest 
                     10: tries to find out whether the file (or device)
                     11: .I filename
                     12: is a CVF. It does so by reading the first 512 bytes from
                     13: .I filename
                     14: and checking for certain strings.
                     15: 
                     16: If
                     17: .I filename
                     18: is just a minus sign (-) the data are read from standard input.
                     19: 
                     20: If the switch
                     21: .I -v
                     22: is given the result of the test is printed to standard output including
                     23: a description about what kind of CVF was detected.
                     24: 
                     25: .SH RETURN VALUES
                     26: .I cvftest 
                     27: returns zero (i.e. true) if 
                     28: .I filename
                     29: has been recognized as a CVF. Otherwise it returns 1. A value >1
                     30: indicates an error (e.g. 
                     31: .I filename
                     32: does not exist or cannot be read).
                     33: 
                     34: .SH BUGS
                     35: This program is so simple that it could be a shell script. But I'm not a shell
                     36: hacker, so it's C.
                     37: 
                     38: The test is not idiot-proof. As it just checks for some magic values, it
                     39: might eventually misidentify other files as CVFs. These cases are supposed
                     40: to be extremely unlikely, though, and have never been reported yet. But if
                     41: you take a look at the source you easily find a way to fool the program :-)
