# Alacritty does not support including other files into
# its configuration yet. As such, this processor needs to
# change the user's configuration file *itself*.
#
# 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] - alacritty color config'
# from which it will delete everything until it finds a line:
# '# Base16End [theme name] - alacritty color config'
# So, if you don't want to lose anything -
# Do NOT put anything important between those two lines.
