def source_code(s, globs, system='sage'):
    r"""
    Format an object's source code to process and display in the
    Sage notebook.

    INPUT:

    - ``s`` - a string; a name of an object

    - ``globs`` - a string:object dictionary; a context in which to
      evaluate ``s``

    - ``system`` - a string (default: 'sage'); the system to which to
      confine the search

    OUTPUT:

    - a string containing the object's file, starting line number, and
      source code
