Outdated egg!
This is an egg for CHICKEN 3, the unsupported old release. You're almost certainly looking for the CHICKEN 4 version of this egg, if it exists.
If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Eggs Unlimited (release branch 3, updated Tue May 25 21:04:35 2010)
A library of extensions for the Chicken Scheme system.
Note: the development of CHICKEN 3 is frozen. Consider using the current CHICKEN version and its corresponding eggs.
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 tarball repository.
