Dos Rar Extractor

Hey,

Does anyone know of any dos rar extrating programs. Ones that take params like this:

c:\>rarprogram myrar.rar

I need this to build into my program so i can extract rar files, or if anyone knows any small standalone win32 ones that could easily be used to extract a rar in the background of a program. I plan to output the program then run it hidden in the background from my program.

Thanks alot
TNT

Here's a paper on the rar format, if you're interested in rolling your own.

Hey thanks id looked at that, but i cant seem to make sense of it yet alone incorperating it into a program.
