+# This script can be run in two different contexts:
+#
+# - From git, when the user invokes the "vimdiff" merge tool. In this context
+# this script expects the following environment variables (among others) to
+# be defined (which is something "git" takes care of):
+#
+# - $BASE
+# - $LOCAL
+# - $REMOTE
+# - $MERGED
+#
+# In this mode, all this script does is to run the next command:
+#
+# vim -f -c ... $LOCAL $BASE $REMOTE $MERGED
+#
+# ...where the "..." string depends on the value of the
+# "mergetool.vimdiff.layout" configuration variable and is used to open vim
+# with a certain layout of buffers, windows and tabs.
+#
+# - From a script inside the unit tests framework folder ("t" folder) by
+# sourcing this script and then manually calling "run_unit_tests", which
+# will run a battery of unit tests to make sure nothing breaks.
+# In this context this script does not expect any particular environment
+# variable to be set.
