guile/module/system/vm/debug.scm
Ludovic Courtes 884d46de23 Tried compiling more code; augmented the doc.
* module/language/Makefile.am: New.

* module/language/scheme/Makefile.am: New.

* configure.in: Produce these two new Makefiles.

* doc/guile-vm.texi: Documented `compile-file', `compiled-file-name', and
  `compile-in'.

* module/system/base/compile.scm: Cosmetic changes.

* module/system/base/language.scm: Likewise.

* module/system/il/Makefile.am: Tried (and failed) to compile more
  things.

* module/system/vm/Makefile.am: All source files in here can now be
  compiled without harming further compilation.

* module/system/vm/assemble.scm: Select only specific bindings from
  `(system vm core)'.
  (dump-object!): Show a more meaningful error message.

* module/system/vm/conv.scm: Select only specific bindings from `(system
  vm core)'.

* module/system/vm/debug.scm: Likewise.

* module/system/vm/frame.scm: Changed the header.  Use a renamer for
  `(system vm core)'.

* src/guilec.in: Added options, via `getopt-long'.
