Article contents:== Outdated egg! This is an egg for CHICKEN 3, the unsupported old release. You're almost certainly looking for [[/eggref/4/index|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 [[https://wiki.call-cc.org/chicken-projects/egg-index-4.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: eggs]] [[toc:]] == 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 [[http://code.call-cc.org|current CHICKEN version]] and its [[http://wiki.call-cc.org/chicken-projects/egg-index-4.html|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 [[http://code.call-cc.org/legacy-eggs/tarballs/|tarball repository]]. === List of available eggs ====
