Eggs Unlimited (release branch 5)

Last updated: Wed Oct 29 06:15:03 2025

A library of extensions for the CHICKEN Scheme system.

Installation

Just enter

  chicken-install EXTENSIONNAME

This will download anything needed to compile and install the library. If your extension repository is placed at a location for which you don't have write permissions, then run chicken-install with the -sudo option or run it as root (not recommended).

You can obtain the repository location by running

  csi -R chicken.platform -p "(repository-path)"

If you only want to download the extension source code, pass the -retrieve option to chicken-install:

  chicken-install -retrieve EXTENSIONNAME

For more information, enter

  chicken-install -help
