Hi, I’m new to IronRuby. I downloaded “IronRuby Alpha” and I am confused  
about the command line options of ir.exe. If I do:

ir.exe -h

It does not even list the option -AI which is used by ir.cmd. Is there a  
list of all the command line options somewhere? Is there a source code  
file I should look into in IronRuby itself?

Thanks,

This option will be removed in the next release.

The file is Ruby\Hosting\RubyOptionsParser.cs

Thanks. I tried the -save option to create a DLL but it doesn’t seem to  
be working?

Right, precompilation is not supported yet. -save is an experimental  
option.

Yes, the -save option C.J. pointed to does create the DLL, but running  
ildasm on it, there’s nothing in there. I’m guessing this is a feature  
that isn’t supported yet and that I will have to write my own DLL  
creation? If so, any hints on how to do this?
