[Stathis Kamperis <ekamperi@xxxxxxxxx>]

Salute,

Here is a patch that extends 'hammer snapls' output:
http://leaf.dragonflybsd.org/~beket/0001-hammer-snapls-Print-more-verbose-output.patch

This is how it looks like with the patch applied:

beket:~% hammer snapls /home /var

(You can compare the output with your current snapls version)

Unless someone objects, I'll push it in a couple of days top.
