How do I get a single NSIS script with parameters?

Hello,

I have one question. I would like to know how it is possible to have a NSIS script accept command line parameters so that it would do different things depending on whether a command line parameter is supplied or not and based on what the command line parameters are. I've been looking at the wiki and the script reference but I couldn't find that anywhere. I imagine if such a feature exists it would work like
"makensis.exe setup.nsi"
to do one thing and
"makensis.exe setup.nsi standalone"
to do another thing

Any assistance would be appreciated.

thanks

You can use the /D switch to supply a define to makensis: http://nsis.sourceforge.net/Docs/Chapter3.html

In your script, then use
!ifdef yourdefine
some code
!else
some other code
!endif
