No problem, as long as you give us enough time for reading your next
proposal version so that you can fix the last things up before the
(now approaching) deadline is here.

Sounds good.

Ok.

Great.

Ok, as long as it does not take too much time that could be used for
working on more important features / integration.

XMP support sounds great, but video files may have embedded meta-data
in other forms, can't they?
Also, python-xmp does not seem to be available in Debian.

If you have good reasons to prefer the "one command-line tool per file
type" way, don't hesitate stating them.

shred is another alternative you might want to consider.
It's shipped by the GNU coreutils package and is thus installed by
default in every GNU/Linux system I think.

Great. The now-shipped-in-Python under the unittest name, right?

Sure. This is an approach I do like.

Ok. Else don't worry, as long as you tell us clearly in advance.

Please don't remove references to your previous work from your
proposal. I was merely asking to understand a bit better how you deal
with code once it's published.

If I understand clearly, this means:

May 23 - June 15th: very busy
June 16th - July 14th: quite busy, 4 hours a day
July 11th - July 15th: Mid-term evaluations
July 15th - August 22nd: Firm 'pencils down' date

Feel free to correct me if needed.

Great. Do you feel you can send us (and the google-melange webapp)
your updated proposal before Wednesday, 06:00pm GMT?

Agreed.

In case you think this can be implemented in, say, <=2 days, and this
does not mean overcommitting, I'd be happy to see this feature make it
into your proposal.

> Do you want to read the newer version when I finish to write it?


I do!

There's a better way to waste my time: submitting a proposal I would
not like as much as I could :)
