+## pre-built, and not deleted by the normal clean rules.  makeinfo is
+## therefore in the category of "special tools" not normally required, which
+## configure does not have to check for (eg autoconf itself).
+## In a CVS checkout on the other hand, the manuals are not included.
+## So makeinfo is a requirement to build from CVS, and configure
+## should test for it as it does for any other build requirement.
+## We use the presence of $srcdir/info/emacs to distinguish a release,
+## with pre-built manuals, from a CVS checkout.
