UPDATE by Peter  G. Aitken

PURPOSE:
         UPDATE takes two file sources, such as a floppy disk and a hard
disk subdirectory, and synchronizes them so both contain the latest version
of your files. This makes it easier to move files between home and work
computers.

FORMAT:
                UPDATE path1/drive path2/drive [options]

At least one of the path/drive parameters must be a path; both cannot be drives.

The option switches for UPDATE are

                /L    Logs file-copy operations

                /Q    Quick mode skips the verify step when a drive is
                       used as a parameter and duplicate filenames are found

The return codes for UPDATE are

                0-Normal program termination
                1-Error opening a file
                2-Error reading from a file
                3-Error creating a file
                4-Error writing to a file]

REMARKS:
        UPDATE removes the tedium of transferring files between your work
and home computer. It can be run unattended in a batch file. When you use
a drive specification as a parameter in a batch file, you must include
the /Q option to avoid being prompted for verification when duplicate
filenames are encountered. This option should be used with extreme care,
since you could potentially replace the wrong versions of files.
