emulator).

This function is used as follows (the order of the first 2 steps is irrelevant):-

- create the process and load the executable (RProcess::Create()),

- create the command line object (CApaCommandLine::NewLC()), and set it up using 

the various setter functions, for instance SetDocumentNameL(),

- call SetProcessEnvironmentL() to assign the command line to the process,

- call Resume() on the process.

Note that this sequence of steps bypasses the application architecture, and is 

not recommended. RApaLsSession::StartApp() is the recommended way to 

launch an application with a command line.
