I'm not a Gentoo developer; this repo is an attempt in making my life easier with my projects and modified ebuilds.
All advices and PR welcomed.
For example, with this kind of file in /etc/portage/repos.conf:
[lqp1]
location = /var/db/repos/lqp1
sync-type = git
sync-uri = https://github.com/lqp1/gentoo-overlay
auto-sync = yes
# to update this overlay only
$ sudo emaint sync -r lqp1
# to update a manifest and push
$ pkgdev manifest
$ git add ...
$ ebuild xxxx clean test install
$ pkgdev commit
$ pkgdev push -n
