i can't believe that there is no way to get a command line other than
from main() function in unix.
utils, like 'ps ax' indicating that its possible :)

At least in windows , there is a GetCommandLine() for that.

One of the things I need to solve is some references to argCnt, argVec, engVec in plugin implementation... I think it is not-good give a plugin access to vm parameters through globals...
