+# v4l2-cli by itself does not accept config file
+# camset allows us to save setting to text file, but it requires GUI to load it, which is inconvinient
+# What I've done
+# So I've written script that allows us to load settings from the config file, created with camset earlier
+# Code is based on Camset (https://github.com/azeam/camset/)
+# Run like: `python cliread.py myconfig.txt` (using myconfig.txt saved by camset)
