-
- * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
- are cloned into that directory using git from \$GNULIB_URL, defaulting

+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+ environment variable or via the --gnulib-srcdir option), then sources
+ are fetched from that local directory. If it is a git repository and

+ and sources are fetched from there. If GNULIB_REFDIR is set (either
+ as an environment variable or via the --gnulib-refdir option) and is
+ a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+ are cloned into that directory using git from \$GNULIB_URL, defaulting
+ to $default_gnulib_url.
+ If the configuration variable GNULIB_REVISION is set in bootstrap.conf,

+ checked out.
+
+If you maintain a package and want to pin a particular revision of the
