The Gentoo developer manual take precedence over any information here.

See Project:Science for more information on the project.


  1. Installation and usage
  1. Contributor guidelies


Manual install

As per the current Portage specifications, ebuild repositories (a.k.a. overlays) can be managed via file collections under /etc/portage/repos.conf/, via the new plug-in sync system.

To enable our overlay without the need for additional software, you first need to have git(1) installed:

emerge --ask --verbose dev-vcs/git 

Then you can add the custom entry for the science repository by downloading the science.conf file

wget \
	-O /etc/portage/repos.conf/science

To start using the overlay you now only need to sync the overlay, via

emaint sync --repo science

or the traditional

emerge --sync

Manual uninstall

To uninstall the overlay simply run:

rm /etc/portage/repos.conf/science
rm /var/db/repos/science -rf

Layman install

You can also install the overlay via the layman overlay manager

layman --add science

Layman uninstall

To delete the overlay run

layman --delete science

Using packages from ::science

To enable the packges from ::science you need to make sure that you are accepting the ~${ARCH} keywords for your respective arch.

Make sure that the /etc/portage/package.accept_keywords/ folder exists and run

printf '*/*::science ~%s' "$(portageq envvar ARCH)" >> /etc/portage/package.accept_keywords/SCIENCE

Generic guidelines for contributors

We are always going to welcome new contributors and love expanding our collection.

For basic guidelines please see our contributing guide.

The GURU Project has created excellent documentation for potential contributors.
We highly advise you to give them a read along with other general Gentoo guidelines

In addition to the above guidelines please make sure that if you submitting a new package, please add the Science Project as an additional maintainer to the package.
For an example, take a look at the metadata for the Numba package - dev-python/numba/metadata.xml
