+Convert between positions (line and column-based) and offsets (range-based)
+locations in a [virtual file][vfile].
+
+## Install
+
+[npm][]:
+
+```sh
+npm install vfile-location
+```
+
+## Usage
+
+```js
+var vfile = require('vfile')
+var vfileLocation = require('vfile-location')
+
+var location = vfileLocation(vfile('foo\nbar\nbaz'))
+
+var offset = location.toOffset({line: 3, column: 3}) // => 10
+location.toPosition(offset) // => {line: 3, column: 3, offset: 10}
+```
+
+## API
+
+### `location = vfileLocation(doc)`
+
+Get transform functions for the given `doc` (`string`) or [`file`][vfile].
+
+Returns an object with [`toOffset`][to-offset] and [`toPosition`][to-position].
+
+### `location.toOffset(position)`
+
+Get the `offset` (`number`) for a line and column-based [`position`][position]
+in the bound file.
+Returns `-1` when given invalid or out of bounds input.
+
+### `location.toPosition(offset)`
+
+Get the line and column-based [`position`][position] for `offset` in the bound
+file.
