This helper script exists to create the generated files that are needed

for a build.  It pretends to be a configure script so that the build
steps are still the normal sequence of ./configure, make, make install
(which is particularly helpful with the samba build farm).  Once the
generated files are ready, the configure.sh script is called to do the
real configure work.

configure

+#!/bin/sh -e
+# This configure script ensures that the configure.sh script exists, and
+# if not, it tries to fetch rsync's generated files or build them.  We
+# then transfer control to the configure.sh script to do the real work.
