# Conventions:
#
# - Follow "Makefile Conventions" from the "GNU Coding Standards" closely.
# However, when something could be improved, don't follow those.
# - Uppercase variables, when referring files, refer to files in this repo.
# - Lowercase variables, when referring files, refer to system files.
# - Lowercase variables starting with '_' refer to absolute paths,
# including $(DESTDIR).
# - Uppercase variables starting with '_' refer to temporary files produced
# in $builddir.
# - Variables ending with '_' refer to a subdir of their parent dir, which
# is in a variable of the same name but without the '_'. The subdir is
# named after this project: <*/man>.
# - Variables ending in '_rm' refer to files that can be removed (exist).
# - Variables ending in '_rmdir' refer to dirs that can be removed (exist).
# - Targets of the form '%-rm' remove their corresponding file '%'.
# - Targets of the form '%/.-rmdir' remove their corresponding dir '%/'.
# - Targets of the form '%/.' create their corresponding directory '%/'.
# - Every file or directory to be created depends on its parent directory.
# This avoids race conditions caused by `mkdir -p`. Only the root
# directories are created with parents.
# - The 'FORCE' target is used to make phony some variables that can't be
# .PHONY to avoid some optimizations.
