which magic numbers? generally there are several log levels, see manpage.

there are two kinds of log output.

1. the user interpretable (default), which is generally a text about
what is going on with a note about the severance (log level)

2. --log-file <filename>, --log-fd <number> enable additional simplified
output .. pretty much like the above but formatted for easier parsing.
unfortunately there is no specific documentation about it, but try it
and compare it to the default out and you'll understand.

I see in documentation, that log files "designed to be easily consumable
by other programs." I think that JSON format will be much better and
easily, because there are many light and fast JSON parsers for different
languages.

that's not an option for light weight backends like the bash based shell
one duply i am maintaining. so yes, as an addition, no as a replacement.

you are welcome to do so, i suggest you to add a --log-format
[plain,json] switch, plain being the default value.
