   4  * Bare bones profiler. Compile with:
   5  *
   6  * linux : gcc -shared -o mono-profiler-sample.so sample.c `pkg-config --cflags --libs mono`
   7  * mac : gcc sample.c -o mono-profiler-sample.dylib -Dmono_free=free -lz `pkg-config --cflags mono-2` -undefined suppress -flat_namespace
   8  *
   9  * Install the binary where the dynamic loader can find it. eg /usr/lib etc
  10  * Then run mono with:
  11  * mono --profile=sample your_application.exe
  12  *
  13  * Note if you name a profiler with more than 8 characters (eg sample6789) appears to not work
