[Paraview] Reader format changes since version 2.4?

[Samuel Crow]

Hello,

I'm making a custom reader for ParaView using a
proprietary custom library.  The most recent print
documentation I have for doing this is the ParaView
Guide version 2.4 .  Is this documentation current
enough?  If not, should I be scrounging through the
source code for something newer to use as an example? 
The format I'm importing from is 3d and will not need
any animation features.

My slower system is a G4 Macintosh with 1 Gig of RAM
and am developing with XCode 2.4.1 although I am
building from makefiles in order to dodge the
restrictions of the XCode project files under CMake. 
I will also be supporting Intel Macintoshes and
Windows-based systems in the near future.

Thanks in advance for any help,

--Sam
