# Respective MANPATH entries would include /usr/local/share/man or $HOME/man.

# This is normally done only on a development host. Through CI and
# package-installer, mlr.1 should be treated as an already-built artifact,
# needing only to be copied to its install dir.
# Copying to man1/mlr1 is so that you can then put the Miller dir in your
# $MANPATH and do "man mlr".
