A command line utility that allows read/write (i.e copy/paste) access to the system clipboard. It does this by wrapping pbcopy/pbpaste (for OSX), xclip (for Linux, FreeBSD, and OpenBSD), and clip (for Windows). Currently works with node.js v0.8+. copy(text[, callback]): asynchronously replaces the current contents of the clip board with text. Takes either a string, array, object, or readable stream. Returns the same value passed in. Optional callback will fire when the copy operation is complete.
