Hi! I wrote Obnam, a backup program (http://liw.fi/obnam/). If you
like the program and would like donate a little, you can send me money
or gifts:

* Amazon wishlist:

* Bitcoin: bitcoin:1FUKDBy79cC6iTaiyg5i1JVBCemiVdb5QC

Obnam does not run on donations: it currently mainly runs on my free
time. Donations are not required in any way: you're more than welcome
to use it without donating, and in any case I prefer a
well-formulated, actionable bug report (see
http://obnam.org/bug-reporting/) or a patch to fix a bug or add a
feature (with appropirate updates to tests). No bug is too small to be
reported.

I can also arrange to do Obnam development for specific features, or
support, for a fee, if you or your company needs something that isn't
happening otherwise.
