+# Allows to use "diff-so-fancy" to compare files that are not controlled by Git.
+# Under the hood it makes use of "git diff" by using the "no-index" option which allows to compare the given two
+# paths/files on the filesystem outside a working tree controlled by Git.
+#
+# @param $1 the path/files to compare
+# @param $2 the path/files to be compared
