        - Added a mapping for *.js files to a Content-Type of
            application/javascript

0.10  Wed, 27 Apr 2016 14:45:00 +0100

        - Reworked how the value for the Content-Type header is
            selected. Simple regexp matching on the path suffix is
            used for *.html?, *.css and *.txt files. Any other files
            are checked using File::LibMagic as before. Closes:
