* 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.
Use module (srfi srfi-13).
Export `use2dot'.
(string-append/separator, mapconcat): Delete.
(vv): Now take list of pairs, and return the mapping..
(>>header): Use `string-join'.
(>>): New proc.
(use2dot): Use `getopt-long'. Use `>>'.
