  Historical/Background information:

  Note that the above list is included only for completeness' sake.
  Also note that you might not want "highest numbered" version of
  Performer, you want the the highest maintenance rev of your main
  release (2.1.X for InfiniteReality and 2.0 otherwise). Note that
  maintenance releases have been done for both 2.0 and 2.1
  simultaneously.

  Systems running IRIX 6.2 or later should load the performer_eoe
  IRIX cd, and performer_dev from the Performer 2.0 CD.  Then load
  the relevant patches as described below.

  The N32 and N64 libraries in Performer 2.0 are not intended for
  systems running IRIX 6.1.  If you require N32 or N64 functionality,
  you need to upgrade to 6.2 (or above) and use 2.0.1 (or above).

  No further releases of Performer are planned for IRIX 4.x or 5.x.

  Performer 1.2 was shipped for both 4.0.5 and 5.2 systems.  If you
  are using IRIS Performer 1.2, only install that version that is
  appropriate for your machine.  The IRIS Performer version is
  indicated by the "IRIX4" or "IRIX5" string in each product name.
  IRIX4 products should only be installed on 4.0.5 systems.   IRIX5
  products can be installed on 5.2, 5.3, 6.0.1, and 6.1 systems.

  When a choice is possible between using Performer 1.2 with IRIX 5.x
  or IRIX 4.0.5, IRIX 5.x is highly preferable.  IRIX 5.3 is the
  current operating system release and contains many bug fixes and
  enhancements utilized by IRIS Performer.   IRIS Performer 1.2/IRIX4
  was intended only for users who are unable to upgrade to IRIX 5.x.
