# This configuration requires dunst version at least 1.8.0!
#
# Dunst now allows drop-in configuration files in a special
# `dunstrc.d/` directory in the usual configuration directory.
# That means we can drop in a specific `00-colorscheme.conf`
# file instead of operating directly on the main dunst
# configuration file.
#
# This will generally not be a problem, though it can lead
# to corrupted configurations in exceptional circumstances
# (such as every line being preceded by the process control
# regex, for whatever reason).
#
# In general, the processor looks for a specific line in the
# following format:
# '# Base16 [theme name] - dunst color config'
# from which it will delete everything until it finds a line:
# '# Base16End [theme name] - dunst color config'
# So, if you don't want to lose anything -
# Do NOT put anything important between those two lines.
