* HACKING: Give an example of how to run a test in isolation.
* README: Fix/simplify example for running a single test.
* README-hacking: Reference the HACKING file.
Prompted by a report from Ed Avis:
<http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/14710>
* README-hacking: Organise LZMA and Valgrind as
as optional requirements rather than in their own sections.
Mention bootstrap will now check tool versions.
* README-prereq: Make a start on specific instructions
for optaining build tools. Currently we just have notes
for Fedora linux.
* bootstrap.conf: Add the list of tools and versions required.
* bootstrap: Add the logic to check for the required tools,
and list all required tools and versions if any are missing.
* README-hacking: Prefer the no-hyphen variant of git commands,
e.g., use "git pull" not "git-pull".
Don't presume that the only way to read this document is via a
prior git clone: provide instructions for cloning coreutils, too.
* README-hacking: Add "cd automake" in build instructions.
From Bob Proulx.
* README-hacking: Build-from-checkout now require Perl, too.
* bootstrap: Now that these generated Makefile.am files are no longer
under version control, they must be created at bootstrap time.
