A CSS minifier which not only aims at reducing the amount of bytes of the
output, but also at improving gzip compression. It may be used as a library,
or a stand-alone executable. For the library, refer to the Hasmin module
documentation. For the program: the output is the minified CSS file, but
hasmin allows also its compression into gzip using Google's Zopfli library.
To use it: ./hasmin input.css > output.css
By default, most minification techniques are enabled. For a list of
available flags, do: ./hasmin --help
