[Wine] Does winetricks run wine?

[notfed]

Hi,

Does winetricks run the wine executable? Reason is, I have several versions of wine installed in separate directories.  I want to know if I need to tell winetricks which version to use. I'd appreciate it if anyone could either tell me that (1) I shouldn't worry about it, it doesn't matter which version of wine is installed, or (2) how to tell winetricks which wine executable to use.

Thanks,
Jay
