UPDATE:   Version 1.6, (C) Copyright PJ Ferencz, 1990-1995

SYNTAX:   update source_spec [target_directory] [switches]

USAGE:    update compares files meeting source_spec with files in the
          target_directory.  If the files in the target_directory are
          either older or missing, then the target_directory is updated
          with the newer files.  If target_directory is not specified,
          then the current directory is assumed.

SWITCHES: /f = freshen existing files only, do not add any new files.
          /a = add new files only, do not freshen any existing files.
          /m = mirror files in target_directory with source_spec.
          /s = include all subdirectories in update.
          /e = create empty subdirectories.
          /p = prompt for confirmation for each file to be updated.
          /v = verbose mode.

NOTES:    - Switches /f, /a and /m cannot be used together.
          - When using the /m switch, any extra files of type source_spec
            which exists in target_directory and not in the source directory
            will be deleted. Newer files WILL also be overwritten!
          - When using the /e switch, the /s switch must also be specified.
