email comments from Andew Sampson, "I've contacted Terrex, and obtained the 2.2 version of their trpage library. The library included a fork of OSG 0.9.8's txp plugin, modified to load 2.1+ txp DBs. I've done the work of incorporating the changes made to OSG's txp plugin since 0.9.8 into Terrex's fork. The forked version is now up-to-date with the changes made to OSG 0.9.9 and 1.0. Terrex made a lot of changes (especially differences in whitespace), so the diff between the forked version and OSG 1.0's txp plugin is yucky. I did my best, but keep in mind that this is the result of a 4-way merge (kinda... terrex-0.9.8, stock-0.9.8, stock-0.9.9, stock-1.0). I really want to see this forked version merged back into the main OSG branch. The new features offered by this version of the plugin (2.1+ support, variable LOD support, bug fixes) are worth the trouble." -- Don Tidrow then took this code and added his work. -- Robert Osfield then fixed all the warnings that abound in the trpage code base.
