## Express utility functions

The [pillarjs](https://github.com/pillarjs) GitHub organization contains a number of modules
for utility functions that may be generally useful.

| [path-to-regexp](https://www.npmjs.com/package/path-to-regexp) | Turn an Express-style path string such as ``/user/:name` into a regular expression.|
| [resolve-path](https://www.npmjs.com/package/resolve-path) | Resolves a relative path against a root path with validation. |
| [router](https://www.npmjs.com/package/router) | Simple middleware-style router. |
