new asf release v0.52

[Jens Schwarzbach]

Dear All,

find an updated asf release on the website https://code.google.com/p/asf/.

Due to a change of policy, downloads are now hosted by google drive.
You will find the link on the project's home page, but also here:

If you have any ideas for introductory tutorials, just drop a note.

Best,
Jens
