+We've opted to keep only the highest-level sources in the repository. This
+eases our maintenance burden, (fewer merges etc.), but imposes more

For example, you have to use the latest stable versions of the maintainer
tools we depend upon, including:
-- Automake
- Autoconf
+- Automake
- Flex
- Gettext
+- Graphviz
- Gzip
+- Help2man
- Perl
- Rsync
- Tar
+- Texinfo
Valgrind is also highly recommended, if it supports
your architecture.
-Bison is written using Bison grammars, so there are bootstrapping
-issues. The bootstrap script attempts to discover when the C code
-generated from the grammars is out of date, and to bootstrap with an
-out-of-date version of the C code, but the process is not foolproof.
-Also, you may run into similar problems yourself if you modify Bison.
+If you're using a GNU/Linux distribution, the easiest way to install the

-Only building the initial full source tree will be a bit painful.
-Later, after synchronizing from the repository a plain 'make' should
-be sufficient. Note, however, that when gnulib is updated, running
-'./bootstrap' again might be needed.
