commit 5d3abe13a7b503393c47883f1aa9ff61879feda4 Author: Sven Eckelmann sven@narfation.org Date: Sat Jul 17 13:01:28 2021 +0200

batctl: man: Reorder and restructure sections

The number of subcommands in batctl increased dramatically in the recent years. But the documentation to the various commands was just added to random positions in the manpage. This made it harder than necessary to look things up.

This can be improved by:

* split the subcommand types in different classes to keep similar functionality next to each other * order subcommands alphabetically
