/etc/portage/repos.conf

Article description::specifies the location and settings for the repositories used by the current system. It can either be a single file or directory of one or more files. It refers to the Gentoo repository and perhaps additional ebuild repositories used on a system.

Format

 * File names can be arbitrary strings of characters with or without suffix, except for expected by.
 * Comments begin with  (no inline comments).
 * Configuration of each repository is specified in a separate file or section starting with . It is recommended that   is the same as the name given in the repo_name file.
 * Attributes are specified in  format.

Attributes supported in the default section

If user or group id is provided, Portage no longer uses owner of the directory.

Usage
If it doesn't exist create it.

(The Handbook however prefers using it as a directory.)

Add ebuild repositories using eselect repository, e.g. the brother-overlay ebuild repository:

Adding a custom repository is described in the Handbook.

Verify the setting using portageq

References in the output to Gentoo main repository come from the defaults in.

The file might then look like

Eselect can also be used as an alternative to mirrorselect --rsync for setting the Gentoo rsync mirror.

Manipulation of other attributes than,   or   seems not supported by eselect repository but could be done manually when needed.
