there was the situation where four directories contained jst two files, of which three directories were aircraft related, and one directory contained test code from Curt that might be better of in SimGear anyhow. This is just a patch to move a bunch of files to new locations. In case of local changes to any of them you can do the following: move replay.[ch]xx from src/Replay to src/Aircraft move control.[ch]xx from src/Control to src/Aircraft move ssgEntityArray.[ch]xx from src/Objects to simgear/screen In addition it has been decided only to use .[ch]xx files in all directories unless it's contained within an FDM specific directory, in which case the author is free to do whatever (s)he wants. In this repspect the following files have been renamed in src/Multiplayer: tiny_xdr.[ch]pp has become tiny_xdr.[ch]xx multiplaymgr.[ch]pp has become multiplaymgr.[ch]xx
