+#### Multiple license files
+
+If more than one `--license-filepath` argument is specified, the checks are
+performed as follows:
+
+1. First, an exact match is pursued, checking the 1st license file, then
+   the 2nd, and so on. If a match is found, the normal behavior is
+   followed, as if the matched license file was the only license file
+   specified.
+
+2. If no exact match is found, then the software resorts to fuzzy matching.
+   Again, as soon as a match is found, the normal behavior is followed, as
+   if the fuzzy-matched license file was the only license file specified.
+
+3. Finally, if neither exact nor fuzzy matches are found, the content of
+   the first license file is inserted.
