+Parser for JavaScript
+---------------------
+
+[](http://travis-ci.org/erikd/language-javascript)
+
+Based (loosely) on language-python
+
+Two Versions
+------------
+
+There are currently two versions:
+
+* 0.5 series : Is a continuation of the 0.5.X.Y series, from the [master]
+(https://github.com/erikd/language-javascript/tree/master) branch of this
+github repository.
+
+* 0.6 and 0.7 series : This has a vastly different and improved AST which makes if far
+more difficult to build an non-sensical Javascript AST. This code is in the
+[new-ast](https://github.com/erikd/language-javascript/tree/new-ast) branch of
+this github repository.
+
+
+How to build
+------------
+
+Make sure your locale supports UTF-8. For example, on most Unix-like platforms,
+you can type:
+
+ export LC_ALL=en_US.UTF-8
+
+Library:
+
+ cabal clean && cabal configure && cabal build
+
+Tests:
+
+ cabal clean && cabal configure -fbuildtests && cabal build
+
+Running the tests
+
+ ./dist/build/runtests/runtests
+
+
+To debug the grammar
+
+ happy -iparse.txt -g -a -d src/Language/JavaScript/Parser/Grammar5.y
+
+This generates src/Language/JavaScript/Parser/Grammar5.hs, delete this
+when done with the debug version
+
+
+UTF8/Unicode version
+--------------------
+
+Alex 3.0 now supports unicode natively, and has been included as a
+dependency in the cabal file.
+
+Note: The generation of the lexical analyser has been separated out,
+ to remove the install-time dependency on Alex. If any changes
+ need to be made to the lexer, the Lexer.x source lies in
+ src-dev, and the runalex.sh script will invoke Alex with the
+ appropriate directories.

+Name: language-javascript
+Version: 0.7.1.0
+Synopsis: Parser for JavaScript
+Description: Parses Javascript into an Abstract Syntax Tree (AST). Initially intended as frontend to hjsmin.
+ .
+ Note: Version 0.5.0 breaks compatibility with prior versions, the AST has been reworked to allow
+ round trip processing of JavaScript.
