+//@ ### sed([options ,] search_regex, replacement, file)
+//@ Available options:
+//@
+//@ + `-i`: Replace contents of 'file' in-place. _Note that no backups will be created!_
+//@
+//@ Examples:
+//@
+//@ ```javascript
+//@ sed('-i', 'PROGRAM_VERSION', 'v0.1.3', 'source.js');
+//@ sed(/.*DELETE_THIS_LINE.*\n/, '', 'source.js');
+//@ ```
+//@
+//@ Reads an input string from `file` and performs a JavaScript `replace()` on the input
+//@ using the given search regex and replacement string or function. Returns the new string after replacement.

+    'i': 'inplace'
+  });

+  else if (typeof replacement === 'number')
