From Rosetta Code

**Library**

This is an example of a library. You may see a list of other libraries used on Rosetta Code at Category:Solutions by Library.

**Go-rcu** is a package which contains some commonly used utility functions written in the Go programming language.

It is designed to assist with writing Rosetta Code tasks in Go so the same code does not have to be written or copy/pasted time and time again thereby bloating a task's program code unnecessarily.

To use it all you need to do is to copy the source code (in the [talk page]) to a text file called *rcu.go* and then place this in a sub-directory called *rcu* of the directory containing the importing program.

Finally, add "rcu" to your imports so the compiler can find it.
