 Requirements
 ~~~~~~~~~~~~

 DMSChecker requires at least Kickstart 2.04. It also requires the
 Bootblock.library v1 and unpack.library v39 to be present in your
 LIBS: assign. Furthermore it requires the Bootblock.brainfile to be
 present in your L: assign. Those are included in this distribution.
 


 Function
 ~~~~~~~~

 DMSChecker was coded for those who wish to check their DMS archives for
 bootblock vira and is therefore a perfect utility for sysop`s.

 It finds the vira using the Bootblock library and it takes 4 arguments.
 
 A=FILE/A     - The file to check. You can also use pattern matching on this
                one. Eg. 'FILE #?.dms'.

 A=ALL/S      - Specify this if you want DMSChecker to enter sub directories.

 C=CRC/S      - Specify this if you the DMS archives to be checked for CRC
                errors.

 E=ERRORDIR/K - A path where the archives with errors or bootblock vira will
                be copied to.

 When scanning the files DMSChecker outputs the filenames and if it finds a
 virus it will (of course) inform you. But if you use DMSChecker from
 within a script matters are a bit different. If DMSChecker finds a
 virus or the CRC check failed it will return to DOS with an exit code of
 10. If both things happen it will return 20. Here is an example script:
 
 .key filename
 .bra {
 .ket }
 
 FAILAT 11
 DMSChecker {filename} CRC E=RAM:
 IF ERROR
    ECHO "Error 20"
 ENDIF
 IF WARN
    ECHO "DMS archive not safe"
 ENDIF

 Basic enough? Please remember that it's somewhat useless using a pattern
 within a script. Why? Well, because the script will only get the result
 of the LAST check of a file!!
