+dnl Define several useful symbols derived from the VERSION file.  A separate
+dnl file is preferred to embedding the version numbers in various scripts.
+dnl (automake is a textbook-example of why the latter is a bad idea, but there
+dnl are others).
+dnl
+dnl The file contents are:
+dnl	libtool-version	release-version	patch-version
+dnl or
+dnl	release-version
+dnl where
+dnl	libtool-version (see ?) consists of 3 integers separated by '.'
+dnl	release-version consists of a major version and minor version
+dnl		separated by '.', optionally followed by a patch-version
+dnl		separated by '-'.  The minor version need not be an
+dnl		integer (but it is preferred).
+dnl	patch-version is an integer in the form yyyymmdd, so ifdef's and
+dnl		scripts can easily compare versions.
+dnl
+dnl If libtool is used, the first form is required, since CF_WITH_LIBTOOL
