+###
+  A script to eliminate redundant variables common in Emscripted code.
+
+  A variable is eliminateable if it matches a leaf of this condition tree:
+
+  Single-def
+    Single-use
+      Uses only simple nodes
+        Uses only local, single-def names
+          *
+        Uses non-local or non-single-def names
+          No flow-controlling statements
+            No references to any deps between def and use
+              *
+    Multi-use
+      Uses only simple nodes
+        Uses only single-def names
+          *
+
+  WARNING(max99x): A round trip through UglifyJS breaks Closure's
+                   ADVANCED_OPTIMIZATIONS, probably due to lack of
+                   differentiation between quoted and unquoted keys.

+<div class="outline-text-2" id="text-1">
+
+
+<p>
+This package implements a general-purpose JavaScript
+parser/compressor/beautifier toolkit.  It is developed on <a href="http://nodejs.org/">NodeJS</a>, but it
+should work on any JavaScript platform supporting the CommonJS module system
+(and if your platform of choice doesn't support CommonJS, you can easily
+implement it, or discard the <code>exports.*</code> lines from UglifyJS sources).
+</p>
+<p>
+The tokenizer/parser generates an abstract syntax tree from JS code.  You
+can then traverse the AST to learn more about the code, or do various
+manipulations on it.  This part is implemented in <a href="../lib/parse-js.js">parse-js.js</a> and it's a
+port to JavaScript of the excellent <a href="http://marijn.haverbeke.nl/parse-js/">parse-js</a> Common Lisp library from <a href="http://marijn.haverbeke.nl/">Marijn Haverbeke</a>.
+</p>
+<p>
+( See <a href="http://github.com/mishoo/cl-uglify-js">cl-uglify-js</a> if you're looking for the Common Lisp version of
+UglifyJS. )
+</p>
+<p>
+The second part of this package, implemented in <a href="../lib/process.js">process.js</a>, inspects and
+manipulates the AST generated by the parser to provide the following:
+</p>
+<ul>
+<li>
+ability to re-generate JavaScript code from the AST.  Optionally
+indented&mdash;you can use this if you want to “beautify” a program that has
+been compressed, so that you can inspect the source.  But you can also run
+our code generator to print out an AST without any whitespace, so you
+achieve compression as well.
+
+</li>
+<li>
+shorten variable names (usually to single characters).  Our mangler will
+analyze the code and generate proper variable names, depending on scope
+and usage, and is smart enough to deal with globals defined elsewhere, or
+with <code>eval()</code> calls or <code>with{}</code> statements.  In short, if <code>eval()</code> or
+<code>with{}</code> are used in some scope, then all variables in that scope and any
+variables in the parent scopes will remain unmangled, and any references
+to such variables remain unmangled as well.
+
+</li>
+<li>
+various small optimizations that may lead to faster code but certainly
+lead to smaller code.  Where possible, we do the following:
+
+<ul>
+<li>
+foo["bar"]  ==&gt;  foo.bar
+
+</li>
+<li>
+remove block brackets <code>{}</code>
+
+</li>
+<li>
+join consecutive var declarations:
+var a = 10; var b = 20; ==&gt; var a=10,b=20;
+
+</li>
+<li>
+resolve simple constant expressions: 1 +2 * 3 ==&gt; 7.  We only do the
+replacement if the result occupies less bytes; for example 1/3 would
+translate to 0.333333333333, so in this case we don't replace it.
+
+</li>
+<li>
+consecutive statements in blocks are merged into a sequence; in many
+cases, this leaves blocks with a single statement, so then we can remove
+the block brackets.
+
+</li>
+<li>
+various optimizations for IF statements:
+
+<ul>
+<li>
+if (foo) bar(); else baz(); ==&gt; foo?bar():baz();
+</li>
+<li>
+if (!foo) bar(); else baz(); ==&gt; foo?baz():bar();
+</li>
+<li>
+if (foo) bar(); ==&gt; foo&amp;&amp;bar();
+</li>
+<li>
+if (!foo) bar(); ==&gt; foo||bar();
+</li>
+<li>
+if (foo) return bar(); else return baz(); ==&gt; return foo?bar():baz();
+</li>
+<li>
+if (foo) return bar(); else something(); ==&gt; {if(foo)return bar();something()}
+
+</li>
+</ul>
+</li>
+<li>
+remove some unreachable code and warn about it (code that follows a
+<code>return</code>, <code>throw</code>, <code>break</code> or <code>continue</code> statement, except
+function/variable declarations).
+</li>
+</ul>
+</li>
+</ul>

+<div class="outline-text-3" id="text-1_1">
+
+
+<p>
+The following transformations can in theory break code, although they're
+probably safe in most practical cases.  To enable them you need to pass the
+<code>--unsafe</code> flag.
+</p>
+
+</div>
+
+<div id="outline-container-1_1_1" class="outline-4">
+<h4 id="sec-1_1_1"><span class="section-number-4">1.1.1</span> Calls involving the global Array constructor </h4>
+<div class="outline-text-4" id="text-1_1_1">
+
+
+<p>
+The following transformations occur:
+</p>
+
+
+
+<pre class="src src-js"><span style="color: #a020f0;">new</span> <span style="color: #228b22;">Array</span>(1, 2, 3, 4)  =&gt; [1,2,3,4]
+Array(a, b, c)         =&gt; [a,b,c]
+<span style="color: #a020f0;">new</span> <span style="color: #228b22;">Array</span>(5)           =&gt; Array(5)
+<span style="color: #a020f0;">new</span> <span style="color: #228b22;">Array</span>(a)           =&gt; Array(a)
+</pre>
+
+
+
+<p>
+These are all safe if the Array name isn't redefined.  JavaScript does allow
+one to globally redefine Array (and pretty much everything, in fact) but I
+personally don't see why would anyone do that.
+</p>
+<p>
+UglifyJS does handle the case where Array is redefined locally, or even
+globally but with a <code>function</code> or <code>var</code> declaration.  Therefore, in the
+following cases UglifyJS <b>doesn't touch</b> calls or instantiations of Array:

+<div class="outline-text-3" id="text-1_4">
+
+
+<p>
+There is a command-line tool that exposes the functionality of this library
+for your shell-scripting needs:
+</p>
+
+
+
+<pre class="src src-sh">uglifyjs [ options... ] [ filename ]
+</pre>
+
+
+
+<p>
+<code>filename</code> should be the last argument and should name the file from which
+to read the JavaScript code.  If you don't specify it, it will read code
+from STDIN.
+</p>
+<p>
+Supported options:
+</p>
+<ul>
+<li>
+<code>-b</code> or <code>--beautify</code> &mdash; output indented code; when passed, additional
+options control the beautifier:
+
+<ul>
+<li>
+<code>-i N</code> or <code>--indent N</code> &mdash; indentation level (number of spaces)
+
+</li>
+<li>
+<code>-q</code> or <code>--quote-keys</code> &mdash; quote keys in literal objects (by default,
+only keys that cannot be identifier names will be quotes).
+
+</li>
+</ul>
+</li>
+<li>
+<code>--ascii</code> &mdash; pass this argument to encode non-ASCII characters as
+<code>\uXXXX</code> sequences.  By default UglifyJS won't bother to do it and will
+output Unicode characters instead.  (the output is always encoded in UTF8,
+but if you pass this option you'll only get ASCII).
+
+</li>
+<li>
+<code>-nm</code> or <code>--no-mangle</code> &mdash; don't mangle variable names
+
+</li>
+<li>
+<code>-ns</code> or <code>--no-squeeze</code> &mdash; don't call <code>ast_squeeze()</code> (which does various
+optimizations that result in smaller, less readable code).
+
+</li>
+<li>
+<code>-mt</code> or <code>--mangle-toplevel</code> &mdash; mangle names in the toplevel scope too
+(by default we don't do this).
+
+</li>
+<li>
+<code>--no-seqs</code> &mdash; when <code>ast_squeeze()</code> is called (thus, unless you pass
+<code>--no-squeeze</code>) it will reduce consecutive statements in blocks into a
+sequence.  For example, "a = 10; b = 20; foo();" will be written as
+"a=10,b=20,foo();".  In various occasions, this allows us to discard the
+block brackets (since the block becomes a single statement).  This is ON
+by default because it seems safe and saves a few hundred bytes on some
+libs that I tested it on, but pass <code>--no-seqs</code> to disable it.
+
+</li>
+<li>
+<code>--no-dead-code</code> &mdash; by default, UglifyJS will remove code that is
+obviously unreachable (code that follows a <code>return</code>, <code>throw</code>, <code>break</code> or
+<code>continue</code> statement and is not a function/variable declaration).  Pass
+this option to disable this optimization.
+
+</li>
+<li>
+<code>-nc</code> or <code>--no-copyright</code> &mdash; by default, <code>uglifyjs</code> will keep the initial
+comment tokens in the generated code (assumed to be copyright information
+etc.).  If you pass this it will discard it.
+
+</li>
+<li>
+<code>-o filename</code> or <code>--output filename</code> &mdash; put the result in <code>filename</code>.  If
+this isn't given, the result goes to standard output (or see next one).
+
+</li>
+<li>
+<code>--overwrite</code> &mdash; if the code is read from a file (not from STDIN) and you
+pass <code>--overwrite</code> then the output will be written in the same file.
+
+</li>
+<li>
+<code>--ast</code> &mdash; pass this if you want to get the Abstract Syntax Tree instead
+of JavaScript as output.  Useful for debugging or learning more about the
+internals.
+
+</li>
+<li>
+<code>-v</code> or <code>--verbose</code> &mdash; output some notes on STDERR (for now just how long
+each operation takes).
+
+</li>
+<li>
+<code>--unsafe</code> &mdash; enable other additional optimizations that are known to be
+unsafe in some contrived situations, but could still be generally useful.
+For now only this:
+
+<ul>
+<li>
+foo.toString()  ==&gt;  foo+""
+
+</li>
+</ul>
+</li>
+<li>
+<code>--max-line-len</code> (default 32K characters) &mdash; add a newline after around
+32K characters.  I've seen both FF and Chrome croak when all the code was
+on a single line of around 670K.  Pass &ndash;max-line-len 0 to disable this
+safety feature.
+
+</li>
+<li>
+<code>--reserved-names</code> &mdash; some libraries rely on certain names to be used, as
+pointed out in issue #92 and #81, so this option allow you to exclude such
+names from the mangler.  For example, to keep names <code>require</code> and <code>$super</code>
+intact you'd specify &ndash;reserved-names "require,$super".
+
+</li>
+<li>
+<code>--inline-script</code> &ndash; when you want to include the output literally in an
+HTML <code>&lt;script&gt;</code> tag you can use this option to prevent <code>&lt;/script</code> from
+showing up in the output.
+
+</li>
+<li>
+<code>--lift-vars</code> &ndash; when you pass this, UglifyJS will apply the following
+transformations (see the notes in API, <code>ast_lift_variables</code>):
+
+<ul>
+<li>
+put all <code>var</code> declarations at the start of the scope
+</li>
+<li>
+make sure a variable is declared only once
+</li>
+<li>
+discard unused function arguments
+</li>
+<li>
+discard unused inner (named) functions
+</li>
+<li>
+finally, try to merge assignments into that one <code>var</code> declaration, if
+possible.
+</li>
+</ul>
+</li>
+</ul>

+
+<div id="outline-container-1_4_1" class="outline-4">
+<h4 id="sec-1_4_1"><span class="section-number-4">1.4.1</span> API </h4>
+<div class="outline-text-4" id="text-1_4_1">
+
+
+<p>
+To use the library from JavaScript, you'd do the following (example for
+NodeJS):
+</p>
+
+
+
+<pre class="src src-js"><span style="color: #a020f0;">var</span> <span style="color: #b8860b;">jsp</span> = require(<span style="color: #bc8f8f;">"uglify-js"</span>).parser;
+<span style="color: #a020f0;">var</span> <span style="color: #b8860b;">pro</span> = require(<span style="color: #bc8f8f;">"uglify-js"</span>).uglify;
+
+<span style="color: #a020f0;">var</span> <span style="color: #b8860b;">orig_code</span> = <span style="color: #bc8f8f;">"... JS code here"</span>;
+<span style="color: #a020f0;">var</span> <span style="color: #b8860b;">ast</span> = jsp.parse(orig_code); <span style="color: #b22222;">// </span><span style="color: #b22222;">parse code and get the initial AST
+</span>ast = pro.ast_mangle(ast); <span style="color: #b22222;">// </span><span style="color: #b22222;">get a new AST with mangled names
+</span>ast = pro.ast_squeeze(ast); <span style="color: #b22222;">// </span><span style="color: #b22222;">get an AST with compression optimizations
+</span><span style="color: #a020f0;">var</span> <span style="color: #b8860b;">final_code</span> = pro.gen_code(ast); <span style="color: #b22222;">// </span><span style="color: #b22222;">compressed code here
+</span></pre>
+
+
+
+<p>
+The above performs the full compression that is possible right now.  As you
+can see, there are a sequence of steps which you can apply.  For example if
+you want compressed output but for some reason you don't want to mangle
+variable names, you would simply skip the line that calls
+<code>pro.ast_mangle(ast)</code>.
+</p>
+<p>
+Some of these functions take optional arguments.  Here's a description:
+</p>
+<ul>
+<li>
+<code>jsp.parse(code, strict_semicolons)</code> &ndash; parses JS code and returns an AST.
+<code>strict_semicolons</code> is optional and defaults to <code>false</code>.  If you pass
+<code>true</code> then the parser will throw an error when it expects a semicolon and
+it doesn't find it.  For most JS code you don't want that, but it's useful
+if you want to strictly sanitize your code.
+
+</li>
+<li>
+<code>pro.ast_lift_variables(ast)</code> &ndash; merge and move <code>var</code> declarations to the
+scop of the scope; discard unused function arguments or variables; discard
+unused (named) inner functions.  It also tries to merge assignments
+following the <code>var</code> declaration into it.
+
+<p>
+If your code is very hand-optimized concerning <code>var</code> declarations, this
+lifting variable declarations might actually increase size.  For me it
+helps out.  On jQuery it adds 865 bytes (243 after gzip).  YMMV.  Also
+note that (since it's not enabled by default) this operation isn't yet
+heavily tested (please report if you find issues!).
+</p>
+<p>
+Note that although it might increase the image size (on jQuery it gains
+865 bytes, 243 after gzip) it's technically more correct: in certain
+situations, dead code removal might drop variable declarations, which
+would not happen if the variables are lifted in advance.
+</p>
+<p>
+Here's an example of what it does:
+</p>
+</li>
+</ul>

+
+<ul>
+<li>
+<code>pro.ast_mangle(ast, options)</code> &ndash; generates a new AST containing mangled
+(compressed) variable and function names.  It supports the following
+options:
+
+<ul>
+<li>
+<code>toplevel</code> &ndash; mangle toplevel names (by default we don't touch them).
+</li>
+<li>
+<code>except</code> &ndash; an array of names to exclude from compression.

+</li>
+<li>
+<code>pro.ast_squeeze(ast, options)</code> &ndash; employs further optimizations designed
+to reduce the size of the code that <code>gen_code</code> would generate from the
+AST.  Returns a new AST.  <code>options</code> can be a hash; the supported options
+are:
+
+<ul>
+<li>
+<code>make_seqs</code> (default true) which will cause consecutive statements in a
+block to be merged using the "sequence" (comma) operator
+
+</li>
+<li>
+<code>dead_code</code> (default true) which will remove unreachable code.
+
+</li>
+</ul>
+</li>
+<li>
+<code>pro.gen_code(ast, options)</code> &ndash; generates JS code from the AST.  By
+default it's minified, but using the <code>options</code> argument you can get nicely
+formatted output.  <code>options</code> is, well, optional :-) and if you pass it it
+must be an object and supports the following properties (below you can see
+the default values):
+
+<ul>
+<li>
+<code>beautify: false</code> &ndash; pass <code>true</code> if you want indented output
+</li>
+<li>
+<code>indent_start: 0</code> (only applies when <code>beautify</code> is <code>true</code>) &ndash; initial
+indentation in spaces
+</li>
+<li>
+<code>indent_level: 4</code> (only applies when <code>beautify</code> is <code>true</code>) --
+indentation level, in spaces (pass an even number)
+</li>
+<li>
+<code>quote_keys: false</code> &ndash; if you pass <code>true</code> it will quote all keys in
+literal objects
+</li>
+<li>
+<code>space_colon: false</code> (only applies when <code>beautify</code> is <code>true</code>) &ndash; wether
+to put a space before the colon in object literals
+</li>
+<li>
+<code>ascii_only: false</code> &ndash; pass <code>true</code> if you want to encode non-ASCII
+characters as <code>\uXXXX</code>.
+</li>
+<li>
+<code>inline_script: false</code> &ndash; pass <code>true</code> to escape occurrences of
+<code>&lt;/script</code> in strings

+The beautifier can be used as a general purpose indentation tool.  It's
+useful when you want to make a minified file readable.  One limitation,
+though, is that it discards all comments, so you don't really want to use it
+to reformat your code, unless you don't have, or don't care about, comments.
+</p>
+<p>
+In fact it's not the beautifier who discards comments &mdash; they are dumped at
+the parsing stage, when we build the initial AST.  Comments don't really
+make sense in the AST, and while we could add nodes for them, it would be
+inconvenient because we'd have to add special rules to ignore them at all

+

+<p>
+Unfortunately, for the time being there is no automated test suite.  But I
+ran the compressor manually on non-trivial code, and then I tested that the
+generated code works as expected.  A few hundred times.
+</p>
+<p>
+DynarchLIB was started in times when there was no good JS minifier.
+Therefore I was quite religious about trying to write short code manually,
+and as such DL contains a lot of syntactic hacks<sup><a class="footref" name="fnr.1" href="#fn.1">1</a></sup> such as “foo == bar ?  a
+= 10 : b = 20”, though the more readable version would clearly be to use
+“if/else”.
+</p>
+<p>
+Since the parser/compressor runs fine on DL and jQuery, I'm quite confident
+that it's solid enough for production use.  If you can identify any bugs,
+I'd love to hear about them (<a href="http://groups.google.com/group/uglifyjs">use the Google Group</a> or email me directly).

+#+AUTHOR: Mihai Bazon
+#+EMAIL: mihai.bazon@gmail.com
+
+* UglifyJS --- a JavaScript parser/compressor/beautifier
+
+This package implements a general-purpose JavaScript
+parser/compressor/beautifier toolkit.  It is developed on [[http://nodejs.org/][NodeJS]], but it
+should work on any JavaScript platform supporting the CommonJS module system
+(and if your platform of choice doesn't support CommonJS, you can easily
+implement it, or discard the =exports.*= lines from UglifyJS sources).
+
+The tokenizer/parser generates an abstract syntax tree from JS code.  You
+can then traverse the AST to learn more about the code, or do various
+manipulations on it.  This part is implemented in [[../lib/parse-js.js][parse-js.js]] and it's a
+port to JavaScript of the excellent [[http://marijn.haverbeke.nl/parse-js/][parse-js]] Common Lisp library from [[http://marijn.haverbeke.nl/][Marijn
+Haverbeke]].
+
+( See [[http://github.com/mishoo/cl-uglify-js][cl-uglify-js]] if you're looking for the Common Lisp version of
+UglifyJS. )
+
+The second part of this package, implemented in [[../lib/process.js][process.js]], inspects and
+manipulates the AST generated by the parser to provide the following:
+
+- ability to re-generate JavaScript code from the AST.  Optionally
+  indented---you can use this if you want to “beautify” a program that has
+  been compressed, so that you can inspect the source.  But you can also run
+  our code generator to print out an AST without any whitespace, so you
+  achieve compression as well.
+
+- shorten variable names (usually to single characters).  Our mangler will
+  analyze the code and generate proper variable names, depending on scope
+  and usage, and is smart enough to deal with globals defined elsewhere, or
+  with =eval()= calls or =with{}= statements.  In short, if =eval()= or
+  =with{}= are used in some scope, then all variables in that scope and any
+  variables in the parent scopes will remain unmangled, and any references
+  to such variables remain unmangled as well.
+
+- various small optimizations that may lead to faster code but certainly
+  lead to smaller code.  Where possible, we do the following:
+
+  - foo["bar"]  ==>  foo.bar
+
+  - remove block brackets ={}=
+
+  - join consecutive var declarations:
+    var a = 10; var b = 20; ==> var a=10,b=20;
+
+  - resolve simple constant expressions: 1 +2 * 3 ==> 7.  We only do the
+    replacement if the result occupies less bytes; for example 1/3 would
+    translate to 0.333333333333, so in this case we don't replace it.
+
+  - consecutive statements in blocks are merged into a sequence; in many
+    cases, this leaves blocks with a single statement, so then we can remove
+    the block brackets.
+
+  - various optimizations for IF statements:
+
+    - if (foo) bar(); else baz(); ==> foo?bar():baz();
+    - if (!foo) bar(); else baz(); ==> foo?baz():bar();
+    - if (foo) bar(); ==> foo&&bar();
+    - if (!foo) bar(); ==> foo||bar();
+    - if (foo) return bar(); else return baz(); ==> return foo?bar():baz();
+    - if (foo) return bar(); else something(); ==> {if(foo)return bar();something()}
+
+  - remove some unreachable code and warn about it (code that follows a
+    =return=, =throw=, =break= or =continue= statement, except
+    function/variable declarations).
+
+** <<Unsafe transformations>>
+
+The following transformations can in theory break code, although they're
+probably safe in most practical cases.  To enable them you need to pass the
+=--unsafe= flag.
+
+*** Calls involving the global Array constructor
+
+The following transformations occur:
+
+#+BEGIN_SRC js
+new Array(1, 2, 3, 4)  => [1,2,3,4]
+Array(a, b, c)         => [a,b,c]
+new Array(5)           => Array(5)
+new Array(a)           => Array(a)
+#+END_SRC
+
+These are all safe if the Array name isn't redefined.  JavaScript does allow
+one to globally redefine Array (and pretty much everything, in fact) but I
+personally don't see why would anyone do that.
+
+UglifyJS does handle the case where Array is redefined locally, or even
+globally but with a =function= or =var= declaration.  Therefore, in the
+following cases UglifyJS *doesn't touch* calls or instantiations of Array:
+
+#+BEGIN_SRC js
+// case 1.  globally declared variable
+  var Array;
+  new Array(1, 2, 3);
+  Array(a, b);
+
+  // or (can be declared later)
+  new Array(1, 2, 3);
+  var Array;
+
+  // or (can be a function)
+  new Array(1, 2, 3);
+  function Array() { ... }
+
+// case 2.  declared in a function
+  (function(){
+    a = new Array(1, 2, 3);
+    b = Array(5, 6);
+    var Array;
+  })();
+
+  // or
+  (function(Array){
+    return Array(5, 6, 7);
+  })();
+
+  // or
+  (function(){
+    return new Array(1, 2, 3, 4);
+    function Array() { ... }
+  })();
+
+  // etc.
+#+END_SRC
+
+*** =obj.toString()= ==> =obj+“”=
+
+** Install (NPM)
+
+UglifyJS is now available through NPM --- =npm install uglify-js= should do
+the job.
+
+** Install latest code from GitHub
+
+#+BEGIN_SRC sh
+## clone the repository
+mkdir -p /where/you/wanna/put/it
+cd /where/you/wanna/put/it
+git clone git://github.com/mishoo/UglifyJS.git
+
+## make the module available to Node
+mkdir -p ~/.node_libraries/
+cd ~/.node_libraries/
+ln -s /where/you/wanna/put/it/UglifyJS/uglify-js.js
+
+## and if you want the CLI script too:
+mkdir -p ~/bin
+cd ~/bin
+ln -s /where/you/wanna/put/it/UglifyJS/bin/uglifyjs
+  # (then add ~/bin to your $PATH if it's not there already)
+#+END_SRC
+
+** Usage
+
+There is a command-line tool that exposes the functionality of this library
+for your shell-scripting needs:
+
+#+BEGIN_SRC sh
+uglifyjs [ options... ] [ filename ]
+#+END_SRC
+
+=filename= should be the last argument and should name the file from which
+to read the JavaScript code.  If you don't specify it, it will read code
+from STDIN.
+
+Supported options:
+
+- =-b= or =--beautify= --- output indented code; when passed, additional
+  options control the beautifier:
+
+  - =-i N= or =--indent N= --- indentation level (number of spaces)
+
+  - =-q= or =--quote-keys= --- quote keys in literal objects (by default,
+    only keys that cannot be identifier names will be quotes).
+
+- =--ascii= --- pass this argument to encode non-ASCII characters as
+  =\uXXXX= sequences.  By default UglifyJS won't bother to do it and will
+  output Unicode characters instead.  (the output is always encoded in UTF8,
+  but if you pass this option you'll only get ASCII).
+
+- =-nm= or =--no-mangle= --- don't mangle variable names
+
+- =-ns= or =--no-squeeze= --- don't call =ast_squeeze()= (which does various
+  optimizations that result in smaller, less readable code).
+
+- =-mt= or =--mangle-toplevel= --- mangle names in the toplevel scope too
+  (by default we don't do this).
+
+- =--no-seqs= --- when =ast_squeeze()= is called (thus, unless you pass
+  =--no-squeeze=) it will reduce consecutive statements in blocks into a
+  sequence.  For example, "a = 10; b = 20; foo();" will be written as
+  "a=10,b=20,foo();".  In various occasions, this allows us to discard the
+  block brackets (since the block becomes a single statement).  This is ON
+  by default because it seems safe and saves a few hundred bytes on some
+  libs that I tested it on, but pass =--no-seqs= to disable it.
+
+- =--no-dead-code= --- by default, UglifyJS will remove code that is
+  obviously unreachable (code that follows a =return=, =throw=, =break= or
+  =continue= statement and is not a function/variable declaration).  Pass
+  this option to disable this optimization.
+
+- =-nc= or =--no-copyright= --- by default, =uglifyjs= will keep the initial
+  comment tokens in the generated code (assumed to be copyright information
+  etc.).  If you pass this it will discard it.
+
+- =-o filename= or =--output filename= --- put the result in =filename=.  If
+  this isn't given, the result goes to standard output (or see next one).
+
+- =--overwrite= --- if the code is read from a file (not from STDIN) and you
+  pass =--overwrite= then the output will be written in the same file.
+
+- =--ast= --- pass this if you want to get the Abstract Syntax Tree instead
+  of JavaScript as output.  Useful for debugging or learning more about the
+  internals.
+
+- =-v= or =--verbose= --- output some notes on STDERR (for now just how long
+  each operation takes).
+
+- =--unsafe= --- enable other additional optimizations that are known to be
+  unsafe in some contrived situations, but could still be generally useful.
+  For now only this:
+
+  - foo.toString()  ==>  foo+""
+
+- =--max-line-len= (default 32K characters) --- add a newline after around
+  32K characters.  I've seen both FF and Chrome croak when all the code was
+  on a single line of around 670K.  Pass --max-line-len 0 to disable this
+  safety feature.
+
+- =--reserved-names= --- some libraries rely on certain names to be used, as
+  pointed out in issue #92 and #81, so this option allow you to exclude such
+  names from the mangler.  For example, to keep names =require= and =$super=
+  intact you'd specify --reserved-names "require,$super".
+
+- =--inline-script= -- when you want to include the output literally in an
+  HTML =<script>= tag you can use this option to prevent =</script= from
+  showing up in the output.
+
+- =--lift-vars= -- when you pass this, UglifyJS will apply the following
+  transformations (see the notes in API, =ast_lift_variables=):
+
+  - put all =var= declarations at the start of the scope
+  - make sure a variable is declared only once
+  - discard unused function arguments
+  - discard unused inner (named) functions
+  - finally, try to merge assignments into that one =var= declaration, if
+    possible.
+
+*** API
+
+To use the library from JavaScript, you'd do the following (example for
+NodeJS):
+
+#+BEGIN_SRC js
+var jsp = require("uglify-js").parser;
+var pro = require("uglify-js").uglify;
+
+var orig_code = "... JS code here";
+var ast = jsp.parse(orig_code); // parse code and get the initial AST
+ast = pro.ast_mangle(ast); // get a new AST with mangled names
+ast = pro.ast_squeeze(ast); // get an AST with compression optimizations
+var final_code = pro.gen_code(ast); // compressed code here
+#+END_SRC
+
+The above performs the full compression that is possible right now.  As you
+can see, there are a sequence of steps which you can apply.  For example if
+you want compressed output but for some reason you don't want to mangle
+variable names, you would simply skip the line that calls
+=pro.ast_mangle(ast)=.
+
+Some of these functions take optional arguments.  Here's a description:
+
+- =jsp.parse(code, strict_semicolons)= -- parses JS code and returns an AST.
+  =strict_semicolons= is optional and defaults to =false=.  If you pass
+  =true= then the parser will throw an error when it expects a semicolon and
+  it doesn't find it.  For most JS code you don't want that, but it's useful
+  if you want to strictly sanitize your code.
+
+- =pro.ast_lift_variables(ast)= -- merge and move =var= declarations to the
+  scop of the scope; discard unused function arguments or variables; discard
+  unused (named) inner functions.  It also tries to merge assignments
+  following the =var= declaration into it.
+
+  If your code is very hand-optimized concerning =var= declarations, this
+  lifting variable declarations might actually increase size.  For me it
+  helps out.  On jQuery it adds 865 bytes (243 after gzip).  YMMV.  Also
+  note that (since it's not enabled by default) this operation isn't yet
+  heavily tested (please report if you find issues!).
+
+  Note that although it might increase the image size (on jQuery it gains
+  865 bytes, 243 after gzip) it's technically more correct: in certain
+  situations, dead code removal might drop variable declarations, which
+  would not happen if the variables are lifted in advance.
+
+  Here's an example of what it does:
+
+#+BEGIN_SRC js
+function f(a, b, c, d, e) {
+    var q;
+    var w;
+    w = 10;
+    q = 20;
+    for (var i = 1; i < 10; ++i) {
+        var boo = foo(a);
+    }
+    for (var i = 0; i < 1; ++i) {
+        var boo = bar(c);
+    }
+    function foo(){ ... }
+    function bar(){ ... }
+    function baz(){ ... }
+}
+
+// transforms into ==>
+
+function f(a, b, c) {
+    var i, boo, w = 10, q = 20;
+    for (i = 1; i < 10; ++i) {
+        boo = foo(a);
+    }
+    for (i = 0; i < 1; ++i) {
+        boo = bar(c);
+    }
+    function foo() { ... }
+    function bar() { ... }
+}
+#+END_SRC
+
+- =pro.ast_mangle(ast, options)= -- generates a new AST containing mangled
+  (compressed) variable and function names.  It supports the following
+  options:
+
+  - =toplevel= -- mangle toplevel names (by default we don't touch them).
+  - =except= -- an array of names to exclude from compression.
+
+- =pro.ast_squeeze(ast, options)= -- employs further optimizations designed
+  to reduce the size of the code that =gen_code= would generate from the
+  AST.  Returns a new AST.  =options= can be a hash; the supported options
+  are:
+
+  - =make_seqs= (default true) which will cause consecutive statements in a
+    block to be merged using the "sequence" (comma) operator
+
+  - =dead_code= (default true) which will remove unreachable code.
+
+- =pro.gen_code(ast, options)= -- generates JS code from the AST.  By
+  default it's minified, but using the =options= argument you can get nicely
+  formatted output.  =options= is, well, optional :-) and if you pass it it
+  must be an object and supports the following properties (below you can see
+  the default values):
+
+  - =beautify: false= -- pass =true= if you want indented output
+  - =indent_start: 0= (only applies when =beautify= is =true=) -- initial
+    indentation in spaces
+  - =indent_level: 4= (only applies when =beautify= is =true=) --
+    indentation level, in spaces (pass an even number)
+  - =quote_keys: false= -- if you pass =true= it will quote all keys in
+    literal objects
+  - =space_colon: false= (only applies when =beautify= is =true=) -- wether
+    to put a space before the colon in object literals
+  - =ascii_only: false= -- pass =true= if you want to encode non-ASCII
+    characters as =\uXXXX=.
+  - =inline_script: false= -- pass =true= to escape occurrences of
+    =</script= in strings
+
+*** Beautifier shortcoming -- no more comments
+
+The beautifier can be used as a general purpose indentation tool.  It's
+useful when you want to make a minified file readable.  One limitation,
+though, is that it discards all comments, so you don't really want to use it
+to reformat your code, unless you don't have, or don't care about, comments.
+
+In fact it's not the beautifier who discards comments --- they are dumped at
+the parsing stage, when we build the initial AST.  Comments don't really
+make sense in the AST, and while we could add nodes for them, it would be
+inconvenient because we'd have to add special rules to ignore them at all
+the processing stages.
+
+** Compression -- how good is it?
+
+Here are updated statistics.  (I also updated my Google Closure and YUI
+installations).
+
+We're still a lot better than YUI in terms of compression, though slightly
+slower.  We're still a lot faster than Closure, and compression after gzip
+is comparable.

+
+** Bugs?
+
+Unfortunately, for the time being there is no automated test suite.  But I
+ran the compressor manually on non-trivial code, and then I tested that the
+generated code works as expected.  A few hundred times.
+
+DynarchLIB was started in times when there was no good JS minifier.
+Therefore I was quite religious about trying to write short code manually,
+and as such DL contains a lot of syntactic hacks[1] such as “foo == bar ?  a
+= 10 : b = 20”, though the more readable version would clearly be to use
+“if/else”.
+
+Since the parser/compressor runs fine on DL and jQuery, I'm quite confident
+that it's solid enough for production use.  If you can identify any bugs,
+I'd love to hear about them ([[http://groups.google.com/group/uglifyjs][use the Google Group]] or email me directly).
+
+[1] I even reported a few bugs and suggested some fixes in the original
+    [[http://marijn.haverbeke.nl/parse-js/][parse-js]] library, and Marijn pushed fixes literally in minutes.

+/***********************************************************************
+
+  A JavaScript tokenizer / parser / beautifier / compressor.
+
+  This version is suitable for Node.js.  With minimal changes (the
+  exports stuff) it should work on any JS platform.
+
+  This file contains the tokenizer/parser.  It is a port to JavaScript
+  of parse-js [1], a JavaScript parser library written in Common Lisp
+  by Marijn Haverbeke.  Thank you Marijn!
+
+  [1] http://marijn.haverbeke.nl/parse-js/
+
+  Exported functions:
+
+    - tokenizer(code) -- returns a function.  Call the returned
+      function to fetch the next token.
+
+    - parse(code) -- returns an AST of the given JavaScript code.

+/***********************************************************************
+
+  A JavaScript tokenizer / parser / beautifier / compressor.
+
+  This version is suitable for Node.js.  With minimal changes (the
+  exports stuff) it should work on any JS platform.
+
+  This file implements some AST processors.  They work on data built
+  by parse-js.
+
+  Exported functions:
+
+    - ast_mangle(ast, options) -- mangles the variable/function names
+      in the AST.  Returns an AST.
+
+    - ast_squeeze(ast) -- employs various optimizations to make the
+      final generated code even smaller.  Returns an AST.
+
+    - gen_code(ast, options) -- generates JS code from the AST.  Pass
+      true (or an object, see the code for some options) as second
+      argument to get "pretty" (indented) code.
