/*
Compiling
---------
* Windows (MSVC) - add lib/Remotery.c and lib/Remotery.h to your program. Set include
directories to add Remotery/lib path. The required library ws2_32.lib should be picked
up through the use of the #pragma comment(lib, "ws2_32.lib") directive in Remotery.c.
* Mac OS X (XCode) - simply add lib/Remotery.c and lib/Remotery.h to your program.
* Linux (GCC) - add the source in lib folder. Compilation of the code requires -pthreads for
library linkage. For example to compile the same run: cc lib/Remotery.c sample/sample.c
-I lib -pthread -lm
You can define some extra macros to modify what features are compiled into Remotery. These are
documented just below this comment.
