You can explicitly provide a full path to the tool by setting the
configuration variable `mergetool.<tool>.path`. For example, you
can configure the absolute path to kdiff3 by setting
-`mergetool.kdiff3.path`. Otherwise, 'git-mergetool' assumes the

+These are safe to remove once a file has been merged and its
