Makefile.COMMON

# * NAME    - vanity
#
# Many of the variables defined below are defined conditionally (using '?'),
# which allows the project's main Makefile to override any of these settings, if
# needed. See also:
#
# https://www.gnu.org/software/make/manual/html_node/Flavors.html#Flavors.
#
# The including Makefile may define any number of extra targets that are
# specific to that project.
#
# Many inspiration has been taken from:
