+ --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 dowloading
+                              them again.
+ --cvs-auth=METHOD            Set the CVS access method used for downloading
+                              gnulib files. METHOD is one of the keywords
+                              accepted by cvs -d option (see info cvs
+                              repository).
+ --cvs-user=USERNAME          Set the CVS username to be used when accessing
+                              the gnulib repository.
+ --no-po                      Do not download po files.
+
+Running without arguments will suffice in most cases. It is equivalent
+to 
+
+    ./bootstrap --cvs-auth=ext --cvs-user=anoncvs
