Yes i like this. Perhaps something like:

binman ls-files output   - to list output files

We could also create a binman.filelist file in the target directory.

The interesting question is how to implement it. It might be best to
add a new method to Entry() which returns a list of output filenames.
Then we can simply call all the entries recursively to get the list,
as we do with other things today.

The other issue is temporary files, which are currently lumped into
the same output dir. One day I think we should distinguish between
output files that produce something useful and files that are just
there for debugging (e.g. the input file used for compression or
signing). The latter could go in a separate binman-working/ directory
inside the output dir, and could be removed wholesale.

Regards,
Simon
