+# Take a dynamically linked ELF binary and relink it, maximizing the
+# use of static libraries.
+#
+# Example:
+#   binary foo
+#            ---> dynamically links to libbar.so.0
+#            ---> dynamically links to libzab.so.3
+# If libbar.a is available, but there is no libzab.a, then we would
+# end up with:
+#   binary foo.static with libbar.a statically inside it
+#            ---> still dynamically linking with libzab.so.3
+#
+# We need to have access to the original link command.  This script
+# works by post-processing it to find the '-lbar' arguments, which are
+# replaced sometimes by direct static library names.
+#
+# Therefore to use this, you have to add this rule to your
+# Makefile.am:
+#
+# foo.static$(EXEEXT): $(foo_OBJECTS) $(foo_DEPENDENCIES)
+#   relink-static.sh \
+#   $(foo_LINK) $(foo_OBJECTS) -static $(foo_LDADD) $(foo_LIBS)
