This is a package of "utility" code I wrote. I use it frequently. If you have received one of my other packages from github (ansiterm, bits, etc ...) you may have gotten mdr as a dependency. It pulls in a fairly large range of standard lib packages so if you only need a smallish set of things it might make sense to just copy them individually or possibly make a package subset from mdr. If you find it useful - or find a bug - please send an email.

Installation

If you have a working go installation on a Unix-like OS:

go get github.com/hotei/mdr
