The most important thing to know about noclip is that this software is named after a common cheat code. It was originally called unclip, but I realized after the fact that noclip is a cooler name and a little bit easier to type.
Noclip has two usage modes:
noclip c activates copy mode, which stores in the clipboard whatever you pipe to stdin. noclip v activates paste mode, which prints to stdout whatever is on the clipboard.
God knows what this does with anything other than text. Have fun!
