+# common-path-prefix
+
+Computes the longest prefix string that is common to each path, excluding the
+base component. Tested with Node 0.10 and above.
+
+## Installation
+
+```
+npm install --save common-path-prefix
+```
+
+## Usage
+
+The module has one default export, the `commonPathPrefix` function:
+
+```js
+var commonPathPrefix = require('common-path-prefix')
+```
+
+Call `commonPathPrefix()` with an array of paths (strings) and an optional
+separator character:
+
+```js
+var paths = ['templates/main.handlebars', 'templates/_partial.handlebars']
+
+commonPathPrefix(paths, '/') // returns 'templates/'
+```
+
+If the separator is not provided the first `/` or `\` found in the first path
+string is used. This means the module works correctly no matter the platform:
+
+```js
+commonPathPrefix(['templates/main.handlebars', 'templates/_partial.handlebars']) // returns 'templates/'
+commonPathPrefix(['templates\\main.handlebars', 'templates\\_partial.handlebars']) // returns 'templates\\'
+```
+
+You can provide any separator, for example:
+
+```js
+commonPathPrefix(['foo$bar', 'foo$baz'], '$') // returns 'foo$''
+```
+
+An empty string is returned if no common prefix exists:
+
+```js
+commonPathPrefix(['foo/bar', 'baz/qux']) // returns ''
+```
+
+Note that the following *does* have a common prefix:
+
+```js
+commonPathPrefix(['/foo/bar', '/baz/qux']) // returns '/'
+```
