Sometimes old projects are back. Made some updates for my utility, which is used to control brightness of a display, connected to the #Thinkpad X220/X230 via the AGAN X230 board (from AliExpress):- Since I'm using Awesome WM and don't want to write a logic to change brightness on the Lua, I added the --increase-brightness / --decrease-brightness options to change it by one step.- Add option --percent to display current brightness level not as internal value from board, but as percentage.- Update man page, add ChangeLog.For now it is tested under #FreeBSD 14.1-14.3.https://codeberg.org/evgandr/brightness_x220_agan2k#C
