newbie question!

Hi, I've just updated everything from Apache to php and mysql and installed pear on my development NT box! Eventually got pear installed and working (thanks to Thomas schofbeck and his small howto: http://www.t0.or.at/~sunny/php/pear/pear_winstaller.html). I've just installed the Mail_Mime package, and it is showing up in the installed packages list shown using "pear list". However, I can't find the PHP file to include anywhere...shouldn't there be a mimeDecode.php somewhere in the pear\Mail directory? Also, when i try to install mailparse, I get the error "the DSP mailparse.dsp does not exist" - what's that mean!? Any help would be appreciated. Regards Steve Childs.
