guile-tools is a scheme script that loads scheme modules
* 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.
