== chicken-update

A utility program for updating chicken eggs.

=== Usage
 Usage: chicken-update [OPTION ...]
 All other options are passed directly to chicken-install.

       --unknown            try updating eggs with unknown version
       --pin=REGEX          pin eggs matching REGEX
   -h, --help               Display this text


Calling {{chicken-update}} on its own will check
[[http://eggs.call-cc.org/rss-5.xml]] for new egg versions and run
chicken-install if there's a new version available. By default, eggs with an
unknown version are not updated. You can "pin" eggs to prevent them from being
updated by passing a regular expression to the {{--pin}} option. Other options
get passed to {{chicken-install}}.
