Possibility to gather all "ToDos"

Hi,

I'm trying to figure out if there is an easy way to gather all the `@todo something` something to one place/page? It seems my python skills are not up to the task, at least not in a very clumsy way.

The reason I ask, is that it would be really nice to crunch through all the code, see all the fixme things that I have left, gather them in one place to get some overview what needs to be done. Not in a particularly complicated fashion, just something like
## Tasks:
- `todo message` from file `/some/file`
- `another todo` from file `/another/file`

I can give it a shot if you point me in the correct direction.
