Beyond cyclog

# Beyond `cyclog`

The logging services that are supplied out of the box with the package all use the supplied `cyclog` tool.

It is not mandatory to use this, and other logging tools exist that can be easily substituted. These include `multilog`, `multilog`, `svlogd`, and `s6-log`. These tools do more than `cyclog`, which is aimed at covering the most common use case, but by no means all possible use cases. They can do filtering by pattern, compression at rotation time, general post-processing at rotation time (with saved state between rotations), and single-line "status" files.
