  Version      : 2.2
  Release Date : 22.07.1995


  Requirements
  ~~~~~~~~~~~~
  - OS V2.04+ (V37)+ and its libraries
  - superviewsupport.library V3+
  - "xpkmaster.library" V2+ and/or "powerpacker.library" V33+


  Description
  ~~~~~~~~~~~
  Unpack.svobject is an external Library-Module for the
  superview.library V5+.

  I supports reading of XPK- or PowerPacked files and will re-parse
  them through superview.library by creating an temporary, unpacked
  file at the location "VMEM:" and then retrying to do the specific
  operation on the file.

  So this is just a Dummy-SVObject which does for you the work of
  unpacking graphics files before displaying them.
  Writing (packing) of files is not possible.


  Remarks
  ~~~~~~~
  * VMEM:
  * Temporary data will be written to a directory assigned to "VMEM:".

  * Compatibility:
  * Well, this one is not a "real" SVObject and will thus not work
    with Versions below V5 of superview.library.
    It depends on the presence of GfxBuffer-Support and various other
    things. It's just thought to make your life easier, if you've to handle
    many packed files, which you don't want to unpack each time you
    wish to display them.
    Nevertheless it is recommended to work with unpacked files, wherever
    possible. If you wish to pack files with PP20 or XPK, please
    use the SVO-Format for this instead.
