(1) The UPDATE program *only* works with Linux, Win95, AmigaOS, and OS/2.
    See the HVSC web page for link to Amiga version (URL at bottom).  It
    will also work on other UNIX systems, but you will have to email
    shark@dhp.com for the source code.  Mac and WinNT support will
    hopefully occur in the future.

(2) The /update directory should reside directly within the HV SIDs
    Collection.  We recommend the follow for unzipping:

    Win95 -> pkunzip -d hv_up_??.zip
    UNIX  -> unzip hv_up_??.zip -d <destdir>

    NOTE: The recommended command has changed for Linux/Unix users.  That
    is because the -L switch was needed in the ages of the collection being
    MS-DOS (8.3) based.  It is now defunct.

    If the old UPDATE program exists, chose overwrite.  That is, always use
    the newest UPDATE program.  Win95 users make sure to use a decompressor
    that can handle long file names (Winzip 6.3 does the job nicely).

    The updates are doubled zipped in order to allow us to cram more SIDs in.

    More detailed information is given when you run the UPDATE program.

(3) Only run/unzip one update at a time.  That is, don't unzip several
    updates at the same time into the same directory.  Run each update in
    _sequence_ starting with the lower updates.  Further, it is recommended
    that you delete the /update directory after you are successful with the
    update.  The reason is that UPDATE might not run correctly if two /update
    directories that differ in case are present.

(4) It is safe to run the update on your collection even if you have unwisely
    modified the collection or if you only have a partial collection.  If
    any problems occur, an error file will be generated which will list
    the errors.  We recommend that you don't modify HV SIDs.

(5) DO NOT RUN THE SAME UPDATE ON YOUR COLLECTION MORE THAN ONCE!  You
    will damage some SIDs if you do!

(6) Win32 users only: if you have DJGPP installed on your system, make sure
    to set the DJGPP LFN environment variable to 'y'.  LFN stands for long
    file names.  If this variable is not set to 'y', then the Update will
    fail to work correctly.
