Hello, this is Greg from CodeCollaborator Support.
I think the command you are looking for is "addhgdiffs". I have included
a link to our documentation below, but the gist of it is use that
command, and every thing after <review> is sent straight to Hg as
an argument, so anything you can do with hg can be done with our tool. I
am not familiar enough with Hg to give you the exact syntax of the
command (Sorry), but a look at some Hg documentation or a talk with your
local expert should get things sorted out in quick order. If you have
any other questions or this didn't make sense, please respond and I will
do my best to address them.
