Thanks a lot!
I have read the updated man page and indeed looks great! It's too bad it
didn't make it in 2.5, but great work keeping the schedule :)

I have tried compiling git HEAD. There's some incompatibility with librsync
v1.0, perhaps you can check this bug report:

https://bugs.launchpad.net/duplicity/+bug/1416344

I have added the above modification and dar compiled for me (using
librsync-1.0.0-1 from EPEL7 on Centos).

After creating a test archive, I got:

'Dropping delta signature of saved file:'

I assume the code to store signatures in the dar archive is not finished
yet?
If that's so, no problem, but otherwise the message is a bit unclear :)

And I have one last request. Could there be the option of filtering files
that do have signatures by file size?
I know dar already has a lot of options, but using file glob on linux where
names and extensions can hardly be relied upon...
Having something like '--delta-sig-min-size=1M' seems much more useable.
Creating signatures for many small files seems more trouble than it's worth
(much like compressing small files)...

I look forward to testing this feature.

Thanks again and cheers!
