23 FUNCTION
24
25 Prints or checks the version and revision information of a file, library or device.
26
27 INPUTS
28
29 NAME -- name of file, library or device to check. If not given it
30 prints version and revision of Kickstart.
31 MD5SUM -- #FIXME what is that?
32 VERSION -- checks for version and returns error code 5 (warn) if the
33 version of the file is lower.
34 REVISION -- checks for revision and returns error code 5 (warn) if the
35 revision of the file is lower.
36 FILE -- reads from file and ignores currently loaded libraries and devices
37 FULL -- prints additional information
38 RES -- gets version of resident commands
