How to add this repo using layman
=================================
sudo layman -f -o https://git.backbone.ws/portage/overlay/blobs/raw/master/layman.xml -a backbone
Using Backbone's Profiles
=========================
Default Desktop/Laptop Profile
------------------------------
/etc/portage/make.profile/parent:
/var/portage/portage/profiles/default/linux/amd64/13.0
/var/portage/layman/backbone/profiles/desktop
Extreme Desktop/Laptop Profile
--------------------------------------------------------
I'm using it for myself. Not all packages are ready for the profile.
Look at profiles/extreme/profile.bashrc for the exclusions I've added.
/etc/portage/make.profile/parent:
/var/portage/portage/profiles/default/linux/amd64/13.0
/var/portage/layman/backbone/profiles/extreme
Hardened Server Profile
------------------------------
/etc/portage/make.profile/parent:
/var/portage/portage/profiles/hardened/linux/amd64/no-multilib
/var/portage/layman/backbone/profiles/server
Remarks

Also for Desktops/Laptops I'm using backbone-sources:
