21 # This file is the equivalent to vim.coffee. `vim.window` is called
22 # `vim.content` to be consistent with Firefox’s frame script terminology and to
23 # avoid confusion about what it represents. There is one `VimFrame` instance for
24 # each tab. It mostly tries to mimic the `Vim` class in vim.coffee, but also
25 # keeps track of web page state. `VimFrame` is not part of the public API.
