# The 'list' target displays all the available targets and their descriptions in
# the current Makefile. It uses the $(firstword $(MAKEFILE_LIST)) expression to
# get the name of the current Makefile, and then searches for lines starting with
# a word character followed by a colon (target names).
# The grep -v '^#' filters out any lines starting with '#' (comments) that are
# commented out tasks. The -A 1 option lists the line that comes after the matched
# target as well, either the command or a descriptive comment for the task.
