Broken homepage link
Also, some of the links at http://catb.org/~esr/intercal/ appear to be broken. For example, the link to the distribution tarball is http://catb.org/~esr/intercal/intercal-make[1]:%20Entering%20directory%20'/home/esr/public_h +tml/intercal'%200.30%20make[1]:%20Leaving%20directory%20'/home/esr/public_html/intercal'.ta +r.gz which seems to indicate broken scripting.
