[Monotone-devel] Monotone passphrases lua hook

[Matthew A. Nicholson]

Greetings,

Here is a monotonerc file implmenting the get_passphrase hook.  It reads 
a file from the conf dir for the passphrases and expects them to be 
formatted as follows:

address@hidden "This is the passphrase"

It should support multiple passphrases.  This was developed for use with 
my monotone-server debian package, but it should prove useful other 
places as well.  Perhaps this could join the new permissions hooks as 
the default.

P.S. Make sure your passphrases file is only readable by your user (or 
the user you run monotone as) for security reasons.
