+Build tools requirements
+========================
+
+When building and testing directly from the repository it is important to
+have at least automake version 1.10 or later installed. All modern
+distributions should default to the latest version, but it seems that
+Debian's default is still an earlier version:
+
+  Check version
+    # dpkg -l '*automake*'
+
+  Install new version
+    # apt-get install automake1.10
+    # update-alternatives --config automake
+
+
