- Javascript Minifier
-=====================
-
-rJSmin is a javascript minifier written in python.
-
-The minifier is based on the semantics of `jsmin.c by Douglas Crockford`_\.
-
-The module is a re-implementation aiming for speed, so it can be used at
-runtime (rather than during a preprocessing step). Usually it produces the
-same results as the original ``jsmin.c``. It differs in the following ways:
-
-- there is no error detection: unterminated string, regex and comment
-  literals are treated as regular javascript code and minified as such.
-- Control characters inside string and regex literals are left untouched; they
-  are not converted to spaces (nor to \n)
-- Newline characters are not allowed inside string and regex literals, except
-  for line continuations in string literals (ECMA-5).
-- "return /regex/" is recognized correctly.
-- "+ +" and "- -" sequences are not collapsed to '++' or '--'
-- Newlines before ! operators are removed more sensibly
-- rJSmin does not handle streams, but only complete strings. (However, the
-  module provides a "streamy" interface).
-
-Since most parts of the logic are handled by the regex engine it's way
-faster than the original python port of ``jsmin.c`` by Baruch Even. The speed
-factor varies between about 6 and 55 depending on input and python version
-(it gets faster the more compressed the input already is). Compared to the
-speed-refactored python port by Dave St.Germain the performance gain is less
-dramatic but still between 1.2 and 7. See the docs/BENCHMARKS file for
-details.
-
-rjsmin.c is a reimplementation of rjsmin.py in C and speeds it up even more.
-
-Both python 2 and python 3 are supported.
