Fabien Potencier has a new post to his site covering the addition of support for private repositories to the features Symfony Flex provides.

Many Flex early adopters asked for it. The Symfony Flex server now supports private recipes repositories as announced during my keynote at SymfonyCon Cluj.

Creating a repository for your private recipes is easy. Create a regular Github repository (probably a private one) to store the recipes. The directory structure is the same as for the official Flex recipes repositories. Then, register the repository as a recipes repository. Done.

The private repositories will behave just like the other public ones in your application. You can also use them to override aliases. There are a few differences between public and private, however, like auto-merge not being supported.
