Professional IronPython

–D
: Enables application debugging.
–E
: Ignores any environment variables that you specified as part of the Windows environment 
variable setup or on the command line after you started it. Some applications may not run 
after you use this command line switch because they won’t be able to find modules and other 
files they need.
–h
: Displays a complete list of the command line arguments.
–i
: Displays the console after running the script. You can then inspect the results of the 
script using console commands.
–m
module
: Runs library module as a script.
–O
: Tells the interpreter to generate optimized code, which means you can’t perform debugging, 
but the application will run faster.
–OO
: Removes all of the doc strings and applies 
–O
optimizations so that the application runs 
even faster than using the 
–O
command line switch alone.
–Q
arg
: Specifies use of one of several division options. You can use any of these values.
➤➤
–Qold
(default): The precision of the output depends on the operators used. For 
example, if you divide two integers, you get an integer as output.
➤
➤
–Qwarn
: Outputs warnings about a loss of precision when performing division
using integers.
➤
➤
–Qwarnall
: Outputs warnings about all uses of the classic division operator.
➤
➤
–Qnew
: The output is always a precise floating point fraction.
