* module/scripts/use2dot.scm: Load (ice-9 getopt-long) with #:use-module
rather than #:autoload. With the previous #:autoload spec, 'option-ref'
would be unbound due to the new autoload semantics.
* module/scripts/: Add %summary entries, and in many cases,
%include-in-guild-list entries to inhibit a script from appearing in
"guild list". Update list.scm to respect this new variable.
* meta/guile-tools: Changed to be a scheme script. Instead of looking for
executables in a "scripts dir", we just look for modules in (scripts),
and load the modules directly.
* module/Makefile.am:
* module/scripts/: Move the scripts into module/ so they can be compiled.
Rename scripts from `foo' to `foo.scm'.
* libguile/Makefile.am: Invoke the snarf->texi code via guile-tools.
* configure.in:
* .gitignore: Update for changes.
