The Clotho 0.1 release is checked in to the common-lisp.net cvs repository. Follow the instructions at
http://www.common-lisp.net/faq.shtml
if you wish to check out the code. The 0.1 release is tagged Release_0_1. Please note that if you check it out from the CVS repository then you get all the sources and the application bundle, but you do not get the pre-built application; in order to run Clotho from the cvs checkout you must first have a working copy of openmcl 0.14-031220 (or later), with the corresponding darwin-headers, and must follow the included instructions to build Clotho.
Also, after the first build, the OS X Finder may not realize at first that Clotho.app is launchable. To cure this problem, close all Finder windows and, from a Terminal window, execute
touch Clotho.app
on the application bundle. Afterwards the application should launch correctly.
