+.I "--runtime=VERSION"
+Mono supports different runtime versions. The version used depends on the program
+that is being run or on its configuration file (named program.exe.config). This option
+can be used to override such autodetection, by forcing a different runtime version
+to be used. Note that this should only be used to select a later compatible runtime
+version than the one the program was compiled against. A typical usage is for

There are a number of external profilers that have been developed for
Mono, we will update this section to contain the profilers.

+The heap Shot profiler can track all live objects, and references to

+profiler.
+To install you must download the profiler

The Live Type profiler shows at every GC iteration all of the live

It is possible to obtain a stack trace of all the active threads in
Mono by sending the QUIT signal to Mono, you can do this from the
command line, like this:

Where pid is the Process ID of the Mono process you want to examine.

+not be used to monitor or probe a production application. The

+and the application might crash or terminate at any given point
+afterwards.

You can use the MONO_LOG_LEVEL and MONO_LOG_MASK environment variables
to get verbose debugging output about the execution of your
