+
+Gulp plugin for mapping sources of a sourcemap.
+
+## Example
+
+```js
+var mapSources = require('@gulp-sourcemaps/map-sources');
+
+gulp.src(...)
+  .pipe(sourcemaps.init())
+  .pipe(mapSources(function(sourcePath, file) {
+    return '../' + sourcePath;
+  }))
+  .pipe(sourcemaps.write())
+  .pipe(gulp.dest(...))
+```
+
+## API
+
+### `mapSources(mapFn)`
+
+Takes a map function as the only argument. Returns an `objectMode` Transform stream.
+
+#### `mapFn(sourcePath, file)`
+
+The map function is called once per value of the `sources` array of a `sourceMap` attached to each [`Vinyl`][vinyl-url] object passed through the stream.  The map function is called with the `sourcePath` string from the `sources` array and the `file` object it originated from.  The return value replaces the original value in the array.
+
+If a `Vinyl` object doesn't have a `sourceMap` or `sourceMap.sources` property, the file is passed through the stream without having the `mapFn` called.
+
+All `sources` are normalized to use `/` instead of `\\` as path separators.
