Converter from single-file init/rc input formats
For your amusement, I just made a silly converter from a format remotely
like that of OpenRC. Note that unlike slew.rc which is largely
independent of any particular rc(1) feature, this converter depends on
rc(1)'s ability to handle variables with unconventional names (eg.
`timeout-kill' and `data/test') and to easily use dynamically named
variables (eg. `$$_name'). And seriously, if you really find a
single-file format necessary (for marketing reasons :(), I think a
shell-based format would be better than alternatives like systemd units
or immortal `run.yml' files.

Parsing /etc/os-release
For those who might be parsing /etc/os-release, and for those who have seen the way that the nosh toolset does it, in its build system and in the external configuration import subsystem: * https://unix.stackexchange.com/a/433245/5132
