+// The following part of the code determines the CLIENT_BUILD variable.
+// Several mechanisms are used for this:
+// * first, if HAVE_BUILD_INFO is defined, include build.h, a file that is
+// generated by the build environment, possibly containing the output
+// of git-describe in a macro called BUILD_DESC
+// * secondly, if this is an exported version of the code, GIT_ARCHIVE will
+// be defined (automatically using the export-subst git attribute), and
+// GIT_COMMIT will contain the commit id.
+// * then, three options exist for determining CLIENT_BUILD:
+// * if BUILD_DESC is defined, use that literally (output of git-describe)
+// * if not, but GIT_COMMIT is defined, use v[maj].[min].[rev].[build]-g[commit]
+// * otherwise, use v[maj].[min].[rev].[build]-unk
+// finally CLIENT_VERSION_SUFFIX is added
+
+// First, include build.h if requested
