(1) The HVSC Update Tool only works on these platforms:

     - Windows 95, Windows 98
     - Windows NT
     - Linux (Intel, ELF)
     - AmigaOS
     - OS/2

    See the HVSC web page for links to Amiga and OS/2 version (URL at
    bottom). It will also work on other UNIX systems, but you will
    have to email <wazzaw@globalnet.co.uk> for the source code.
    Please also do so if you would like to provide publicly available
    ports of the Update Tool for any other popular operating system.
    MacOS/PowerPC support will hopefully occur in the future.
    
    HVSC Update Tool 2.5 and 2.5.1 are upward compatible with HVSC 2.0.
    If you wish to apply an HVSC update older than this one, you are
    advised to use the latest HVSC Update Tool included in this update.

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

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

    If the old Update Tool exists, choose overwrite. That is, always
    use the newest Update Tool. Win95/98/NT users make sure to use a
    decompressor that can handle long file names (Winzip 6.0 and above
    does the job nicely).

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

    More detailed information is given when you run the Update Tool.

(3) Only run/unzip one update at a time. That is, don't unzip several
    updates at the same time into the same directory. Unzip and run
    each update separately, one after each other and in increasing
    order.
    
    Further, it is recommended that you delete the /update directory
    after you are successful with the update. The reason is that the
    Update Tool might not find the right update directory 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!
