#16 note for doc about SVN and Mac OSX Xcode

[Craig Reynolds]

For users trying to work on OpenSteer on Mac OSX 10.4 (Tiger) with Xcode. This is old news since the current version of OSX is 10.5 (Leopard) but some of us are still living in the past:

SVN revision r187:

Changed OpenSteer project for Xcode (Mac OSX) to "Enable SCM" and select Subversion as "SCM System". (If you are running a version of OS X before 10.5 (Leopard) you may need to install Subversion from http://homepage.mac.com/martinott/ then copy the resulting files from /usr/local/bin to /usr/bin)
