You mean like this?

Use-Libraries:
    common-dylan, exclude: { simple-io };
    io
Use-Modules:
    common-dylan, rename: { debug-message -> log },
          export: log;
    format-out;

It might be simpler to just map each header to a single definer clause rather than a semicolon-separated list of clauses, and keep it as “Use-Library” and “Use-Module”.

I might also suggest adding “Module-Creates” as follows (keeping the noun-verb pattern):

Module-Exports:
    log-to-file
Module-Creates:
    log-formatter, *log-file-name*

Or perhaps call them “Export-Module-Names” and “Create-Module-Names” to keep the verb-noun pattern of “Use-Library” and “Use-Module”.

BUT! Overall, sounds good to me.
