reading patches posted on the forum

Hey, i think i found the solution to one of my questions in a previous post, and there was a maxpatch in the form of:

----------begin_max5_patcher----------
asdfaksldfjasjkldfladjlf
-----------end_max5_patcher-----------

i was wondering how do i use that? i tried copy/paste into a text file and opening that in max, but that did not work..

if someone could please tell me how that works, i'd be very thankful!
