Is the wallet.dat file documented anywhere? I'd like to know what the fields are for and how they're structured. In particular right now I'd like to understand the keymeta and purpose fields.

Thanks much.

FWIW, I pulled down the code today and built it and ran it with no problems.

After pulling the git repo:

cd bitcoin
./autogen.sh
./configure --with_incompatible_bdb
src/bitcoind -server=0

All worked as expected. This is on an up-to-date Jessie.

Good luck,

James
