-Bootstrap this package from the checked-out sources.
-
-Options:
- --gnulib-srcdir=DIRNAME  specify the local directory where gnulib
-                          sources reside.  Use this if you already
-                          have gnulib sources on your machine, and
-                          do not want to waste your bandwidth downloading
-                          them again.  Defaults to \$GNULIB_SRCDIR
- --bootstrap-sync         if this bootstrap script is not identical to
-                          the version in the local gnulib sources,
-                          update this script, and then restart it with
-                          /bin/sh or the shell \$CONFIG_SHELL
- --no-bootstrap-sync      do not check whether bootstrap is out of sync
- --copy                   copy files instead of creating symbolic links
- --force                  attempt to bootstrap even if the sources seem
-                          not to have been checked out
- --no-git                 do not use git to update gnulib.  Requires that
-                          --gnulib-srcdir point to a correct gnulib snapshot
- --skip-po                do not download po files
-
-If the file $me.conf exists in the same directory as this script, its
-contents are read as shell variables to configure the bootstrap.
-
-For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
-are honored.
-
-Running without arguments will suffice in most cases.

+Usage: $me [OPTION]...
+Bootstrap this package from the checked-out sources.
+
+Options:
+ --gnulib-srcdir=DIRNAME  specify the local directory where gnulib
+                          sources reside.  Use this if you already
+                          have gnulib sources on your machine, and
+                          do not want to waste your bandwidth downloading
+                          them again.  Defaults to \$GNULIB_SRCDIR
+ --bootstrap-sync         if this bootstrap script is not identical to
+                          the version in the local gnulib sources,
+                          update this script, and then restart it with
+                          /bin/sh or the shell \$CONFIG_SHELL
+ --no-bootstrap-sync      do not check whether bootstrap is out of sync
+ --copy                   copy files instead of creating symbolic links
+ --force                  attempt to bootstrap even if the sources seem
+                          not to have been checked out
+ --no-git                 do not use git to update gnulib.  Requires that
+                          --gnulib-srcdir point to a correct gnulib snapshot
+ --skip-po                do not download po files
+
+If the file $me.conf exists in the same directory as this script, its
+contents are read as shell variables to configure the bootstrap.
+
+For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
+are honored.
+
+Running without arguments will suffice in most cases.
