Problem autoexecuting yuicompressor in Vim (executing it from any directory)

I made yuicompressor work from the command line.

开发者_如何学GoBut the only thing I didn't understand from this tutorial is this part:

You most install yuicompressor and make yuicompressor executable from any directory.

How do I make it execute from any directory?

You need to put it in your PATH environment variable in Windows or in similar one in other OS'es.
