29 ;; Usage: use2dot [OPTIONS] [FILE ...]
30 ;; Display to stdout a DOT specification that describes module dependencies
33 ;; A top-level `use-modules' form or a `:use-module' `define-module'-component
34 ;; results in a "solid" style edge.
36 ;; An `:autoload' `define-module'-component results in a "dotted" style edge
37 ;; with label "N" indicating that N names are responsible for triggering the
38 ;; autoload. [The "N" label is not implemented.]
40 ;; A top-level `load' or `primitive-load' form results in a a "bold" style
41 ;; edge to a node named with either the file name if the `load' argument is a
42 ;; string, or "[computed in FILE]" otherwise.
45 ;; -m, --default-module MOD -- Set MOD as the default module (for top-level
46 ;; `use-modules' forms that do not follow some
47 ;; `define-module' form in a file). MOD should be
48 ;; be a list or `#f', in which case such top-level
49 ;; `use-modules' forms are effectively ignored.
50 ;; Default value: `(guile-user)'.
