So, after some pointers from #lisp, there are at least
three projects to search for symbol names:
- lispdoc.com, for some books, hyperspec and a bunch of libraries
- l1sp.org, provides redirects for ccl, cffi, cl, clim, clisp, clx, mop, pcl, and sbcl
- lisp-search.acceleration.net, which searches quicklisp packages
- xach.com also has a lookup for hyperspec symbols only
Now we need a meta site for all of them.
