You know, the web site in general seems to suffer from assuming that
everyone has read every part of the site.  Give some thought to what a
new or naive user would normally want to do on arriving at the site.

Similarly, see the About CCL page on the Clozure site.  There are two
subtle links to the actual download, which (with my old eyes) didn't
exactly stand out, and a link to Warren's ACL2 page,

Imagine a web page that said "Download CCL", and led to a page that
said "* for MAC, * for Windows," and so on. and then led in turn to a
page that said "Download the Mac image here, note that 10.4 support is
required to install. Install and run (rebuild-ccl :full t).  For more
details, see 'Installing and using CCL'."
