INTRO

This snippet of code is the XSB multiplayer engine, that is, the code 
responsible for visualizing planes.  It is provided totally as-is with
no guarantees of working or being rmotely useful.

Two files, XPLMMultiplayer.cpp and XPLMPlaneRenderer.cpp implement the
lib.  You must include XPLMMultiplayer.h to use it, and provide a text file
with your plugin to config multiplayer.

HISTORY

PATH NAMES AND CROSS-PLATFORM CODE

Paths for XPMP are always "native".  This means:

- Backslash separators on Windows.
- Forward slash separators on Macintosh and Linux.
- For Macintosh (which has both "HFS" and "Posix" style paths) posix paths
  are used.
  
Clients initializing the library are responsible for passing paths in these
formats.  (Macintosh clients can convert from HFS to Posix using the routine
HFS2PosixPath, which internally uses CFURL for the conversion.)

The X-Plane SDK uses native paths, but on Macintosh uses HFS paths.  XPMP
on Mac converts paths from HFS to Posix at all points of interaction with
the SDK.

The paths in some X-Plane formats like OBJ can often have any directory
separator.  These paths are always partial paths; XPMP converts them to
native separators when they are read in. 

Therefore the following rules should be followed when using/modifying XPMP:

- Always pass native paths to the lib and expect native paths out.
- When getting file paths from external sources (like OBJ files) make them
  native immediately.
- Mac only: In the lib wrap any SDK call with HFS->Posix conversion if 
  needed.
