23 # This GNUmakefile is for GNU Make. It is for convenience, so that
24 # one can run 'make' in an unconfigured source tree. In such a tree,
25 # this file causes GNU Make to first create a standard configuration
26 # with the default options, and then reinvokes itself on the
27 # newly-built Makefile. If the source tree is already configured,
28 # this file defers to the existing Makefile.
30 # If you are using a non-GNU 'make', or if you want non-default build
31 # options, or if you want to build in an out-of-source tree, please
32 # run "configure" by hand. But run autogen.sh first, if the source
33 # was checked out directly from the repository.
