== Eggs Unlimited (release branch 4, updated Sun Apr  5 04:12:38 2009)

A library of extensions for the Chicken Scheme system.

=== Installation

Just enter

  $ chicken-setup 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-setup}} as root. You can obtain the repository location by running

  $ chicken-setup -repository

If you only want to download the extension and install it later, pass the {{-fetch}} option to {{chicken-setup}}:

  $ chicken-setup -fetch EXTENSIONNAME

By default the archive will be unpacked into a temporary directory (named {{EXTENSIONNAME.egg-dir}} and the directory will be removed if the installation completed successfully. To keep the extracted files add {{-keep}} to the options passed to {{chicken-setup}}.

For more information, enter

  $ chicken-setup -help

If you would like to access the subversion repository, see [[eggs tutorial]].

If you are looking for 3rd party libraries used by one the extensions, check out the CHICKEN [[http://www.call-with-current-continuation.org/tarballs/|tarball repository]].
