# usage
# $ cat a.css | ./css_pretty_format > out.css
#
# before begin
# $ npm install -g cssbeautify-cli

# cssbeautify-cli will preserve all of the \n at the end of source
# file. This is why a small preprocessing is necessary. At first one
# \n is added to the end. Then all of \n but one will be removed from
# the end.
