+Subject: [PATCH] Makefile: allow to override the version
+
+The mk-version script makes the assumption that the build process runs
+from a SVN checkout or a Git clone of the vpnc source code. However,
+this is not always the case, for example when you are building from a
+tarball, but inside a larger project that is versioned with Git.
+
+This is typically the case when building vpnc under a tool like
+Buildroot, or potentially other embedded Linux build system: the build
+system tool itself is versioned in Git, downloads tarballs of software
+components and builds them.
+
+In order to support such situations, this commit adjusts the Makefile
+to allow the VERSION variable to be overriden from the make command
+line.
