Well usually I do something and people use it if they wantâ I like to get 
feedback, but feedback must always be taken with a kilogram of salt. In the end 
its always fine for me if not everybody agrees.

I would just like to comment on why I have that Log.show level in there (maybe 
a better name should be found, suggestions welcome). There are (cli) programs 
whose natural duty is to have their output show progress or a kind of console 
intermingled with the log messages â e.g. opam, a build system or a test suite. 
At the time it seemed such "consoles" do actually naturally blend into the 
logging mechanism as the lowest logging level which allows to easily reuse the 
reporting/redirection/quietness control of the logging framework for that 
aswell. Still a little bit unsure whether this should be kept or not though.

Best,

Daniel
