+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.

+Subject: [PATCH] Makefile: provide an option to not build manpages
+
+The process of generating the vpnc.8 man page consists in running the
+vpnc tool itself, and parse its --long-help output. While this is
+perfectly fine when building natively, it fails completely when
+cross-compiling: the vpnc binary that was built cannot be executed on
+the build machine.
+
+In order to support such situations with minimal changes, this patch
+adjusts the Makefile to make it understand a MANS variable. By
+default, it's defined to "vpnc.8", which means the manpage continues
+to be built as usual. However, if it's overriden to be empty, then no
+manpage is built.
