-Checking code you didn't write, such as JavaScript libraries, into your git repo is a common practice, but this often inflates your project's language stats and may even cause your project to be labeled as another language. By default, Linguist treats all of the paths defined in [lib/linguist/vendor.yml](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml) as vendored and therefore doesn't include them in the language statistics for a repository.

+
+%% In Elixir we have three main call syntaxes: with parentheses,
+%% without parentheses and with do blocks. They are represented
+%% in the AST as matched, no_parens and unmatched.
+%%
+%% Calls without parentheses are further divided according to how
+%% problematic they are:
+%%
+%% (a) no_parens_one: a call with one unproblematic argument
+%% (e.g. `f a` or `f g a` and similar) (includes unary operators)
+%%
+%% (b) no_parens_many: a call with several arguments (e.g. `f a, b`)
+%%
+%% (c) no_parens_one_ambig: a call with one argument which is
+%% itself a no_parens_many or no_parens_one_ambig (e.g. `f g a, b`
+%% or `f g h a, b` and similar)
+%%
+%% Note, in particular, that no_parens_one_ambig expressions are
+%% ambiguous and are interpreted such that the outer function has
+%% arity 1 (e.g. `f g a, b` is interpreted as `f(g(a, b))` rather
+%% than `f(g(a), b)`). Hence the name, no_parens_one_ambig.
+%%
+%% The distinction is required because we can't, for example, have
+%% a function call with a do block as argument inside another do
+%% block call, unless there are parentheses:
+%%
+%%   if if true do true else false end do  #=> invalid
+%%   if(if true do true else false end) do #=> valid
+%%
+%% Similarly, it is not possible to nest calls without parentheses
+%% if their arity is more than 1:
+%%
+%%   foo a, bar b, c  #=> invalid
+%%   foo(a, bar b, c) #=> invalid
+%%   foo bar a, b     #=> valid
+%%   foo a, bar(b, c) #=> valid
+%%
+%% So the different grammar rules need to take into account
+%% if calls without parentheses are do blocks in particular
+%% segments and act accordingly.

+= Description =
+
+This module actually include many modules: ngx_tcp_module, ngx_tcp_core_module, ngx_tcp_upstream_module, ngx_tcp_proxy_module, ngx_tcp_websocket_module, ngx_tcp_ssl_module, ngx_tcp_upstream_ip_hash_module. All these modules work together to support TCP proxy with Nginx. I also added other features: ip_hash, upstream server health check, status monitor.
+
+The motivation of writing these modules is Nginx's high performance and robustness. At first, I developed this module just for general TCP proxy. And now, this module is frequently used in websocket reverse proxying. 
+
+Note, You can't use the same listening port with HTTP modules.

+'''default:''' ''ssl_prefer_server_ciphers off''
+
+'''context:''' ''tcp, server''
+
+The server requires that the cipher suite list for protocols SSLv3 and TLSv1 are to be preferred over the client supported cipher suite list.
+
+=== ssl_protocols ===
+
+'''syntax:''' ''ssl_protocols [SSLv2] [SSLv3] [TLSv1] [TLSv1.1] [TLSv1.2]''
+
+'''default:''' ''ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2''
+
+'''context:''' ''tcp, server''
+
+This directive enables the protocol versions specified.
+
+=== ssl_verify_client ===
+
+'''syntax:''' ''ssl_verify_client on|off|optional''
+
+'''default:''' ''ssl_verify_client off''
+
+'''context:''' ''tcp, server''
+
+This directive enables the verification of the client identity. Parameter 'optional' checks the client identity using its certificate in case it was made available to the server.
+
+=== ssl_verify_depth ===
+
+'''syntax:''' ''ssl_verify_depth number''
+
+'''default:''' ''ssl_verify_depth 1''
+
+'''context:''' ''tcp, server''
+
+This directive sets how deep the server should go in the client provided certificate chain in order to verify the client identity.
+
+=== ssl_session_cache ===
+
+'''syntax:''' ''ssl_session_cache off|none|builtin:size and/or shared:name:size''
+
+'''default:''' ''ssl_session_cache off''
+
+'''context:''' ''tcp, server''
+
+The directive sets the types and sizes of caches to store the SSL sessions.
+
+The cache types are:
+
+* off -- Hard off: nginx says explicitly to a client that sessions can not reused.
+* none -- Soft off: nginx says to a client that session can be resued, but nginx actually never reuses them. This is workaround for some mail clients as ssl_session_cache may be used in mail proxy as well as in HTTP server.
+* builtin -- the OpenSSL builtin cache, is used inside one worker process only. The cache size is assigned in the number of the sessions. Note: there appears to be a memory fragmentation issue using this method, please take that into consideration when using this. See "References" below.
+* shared -- the cache is shared between all worker processes. The size of the cache is assigned in bytes: 1 MB cache can contain roughly 4000 sessions. Each shared cache must be given an arbitrary name. A shared cache with a given name can be used in several virtual hosts.
+It's possible to use both types of cache &mdash; builtin and shared &mdash; simultaneously, for example:
+
+<geshi lang="nginx">
+ssl_session_cache  builtin:1000  shared:SSL:10m;
+</geshi>
+
+Bear in mind however, that using only shared cache, i.e., without builtin, should be more effective.
+
+=== ssl_session_timeout ===
+
+'''syntax:''' ''ssl_session_timeout time''
+
+'''default:''' ''ssl_session_timeout 5m''
+
+'''context:''' ''tcp, server''
+
+This directive defines the maximum time during which the client can re-use the previously negotiated cryptographic parameters of the secure session that is stored in the SSL cache.
+
+= Compatibility =
+
+* My test bed is 0.7.65+
+
+= Notes =
+
+The http_response_parse.rl and smtp_response_parse.rl are [http://www.complang.org/ragel/ ragel] scripts , you can edit the script and compile it like this:
+
+<geshi lang="bash">
+    $ ragel -G2 http_response_parse.rl
+    $ ragel -G2 smtp_response_parse.rl
+</geshi>
+
+= TODO =
+
+* refact this module, make it more extendable for adding third-party modules
+* manipulate header like http module's proxy_set_header
+* built-in variable support
+* custom log format
+* syslog support
+* FTP/IRC proxying
+
+= Known Issues =
+
+* This module can't use the same listening port with the HTTP module.
+
+= Changelogs =
+
+== v0.2.0 ==
+
+* add ssl proxy module
+* add websocket proxy module
+* add upstream busyness module
+* add tcp access log module
+
+== v0.19 ==
+
+* add many check methods
+
+== v0.1 ==
+
+* first release

+%   because Prolog doesn't do the occurs check, it will also match
+%   other queues, creating circular lists.  So this should ONLY be
+%   used to make new queues.
+
+make_queue(X-X).
+
+
+
+%   join_queue(Element, OldQueue, NewQueue)
+%   adds the new element at the end of the queue.  The old queue is
+%   side-effected, so you *can't* do
+%	join_queue(1, OldQ, NewQ1),
+%	join_queue(2, OldQ, NewQ2).
+%   There isn't any easy way of doing that, sensible though it might
+%   be.  You *can* do
+%	join_queue(1, OldQ, MidQ),
+%	join_queue(2, MidQ, NewQ).
+%   See list_join_queue.
+
+join_queue(Element, Front-[Element|Back], Front-Back).
+
+
+
+%   list_join_queue(List, OldQueue, NewQueue)
+%   adds the new elements at the end of the queue.  The elements are
+%   added in the same order that they appear in the list, e.g.
+%   list_join_queue([y,z], [a,b,c|M]-M, [a,b,c,y,z|N]-N).
+
+list_join_queue(List, Front-OldBack, Front-NewBack) :-
+	append(List, OldBack, NewBack).
+
+
+
+%   jump_queue(Element, OldQueue, NewQueue)
+%   adds the new element at the front of the list.  Unlike join_queue,
+%	jump_queue(1, OldQ, NewQ1),
+%	jump_queue(2, OldQ, NewQ2)
+%   *does* work, though if you add things at the end of NewQ1 they
+%   will also show up in NewQ2.  Note that
+%	jump_queue(1, OldQ, MidQ),
+%	jump_queue(2, MidQ, NewQ)
+%   makes NewQ start 2, 1, ...
+
+jump_queue(Element, Front-Back, [Element|Front]-Back).
+
+
+
+%   list_jump_queue(List, OldQueue, NewQueue)
+%   adds all the elements of List at the front of the queue.  There  are
+%   two  ways  we might do this.  We could add all the elements one at a
+%   time, so that they would appear at the beginning of the queue in the
+%   opposite order to the order they had in the list, or  we  could  add
+%   them in one lump, so that they have the same order in the  queue  as
+%   in  the  list.   As you can easily add the elements one at a time if
+%   that is what you want, I have chosen the latter.
+
+list_jump_queue(List, OldFront-Back, NewFront-Back) :-
+	append(List, OldFront, NewFront).
+%	reverse(List, OldFront, NewFront).	% for the other definition
+
+
+
+%   head_queue(Queue, Head)
+%   unifies Head with the first element of the queue.  The tricky part
+%   is that we might be at the end of a queue: Back-Back, with Back a
+%   variable, and in that case this predicate should not succeed, as we
+%   don't know what that element is or whether it exists yet.
+
+head_queue(Front-Back, Head) :-
+	Front \== Back,		%  the queue is not empty
+	Front = [Head|_].
+
+
+
+%   serve_queue(OldQueue, Head, NewQueue)
+%   removes the first element of the queue for service.
+
+serve_queue(OldFront-Back, Head, NewFront-Back) :-
+	OldFront \== Back,
+	OldFront = [Head|NewFront].
+
+
+
+%   empty_queue(Queue)
+%   tests whether the queue is empty.  If the back of a queue were
+%   guaranteed to be a variable, we could have
+%	empty_queue(Front-Back) :- var(Front).
+%   but I don't see why you shouldn't be able to treat difference
+%   lists as queues if you want to.
+
+empty_queue(Front-Back) :-
+	Front == Back.
+
+
+
+%   length_queue(Queue, Length)
+%   counts the number of elements currently in the queue.  Note that
+%   we have to be careful in checking for the end of the list, we
+%   can't test for [] the way length(List) does.
+
+length_queue(Front-Back, Length) :-
+	length_queue(Front, Back, 0, N),
+	Length = N.
+
+length_queue(Front, Back, N, N) :-
+	Front == Back, !.
+length_queue([_|Front], Back, K, N) :-
+	L is K+1,
+	length_queue(Front, Back, L, N).
+
+
+
+%   list_to_queue(List, Queue)
+%   creates a new queue with the same elements as List.
+
+list_to_queue(List, Front-Back) :-
+	append(List, Back, Front).
+
+
+
+%   queue_to_list(Queue, List)
+%   creates a new list with the same elements as Queue.
+
+queue_to_list(Front-Back, List) :-
+	queue_to_list(Front, Back, List).
+
+queue_to_list(Front, Back, Ans) :-
+	Front == Back, !, Ans = [].
+queue_to_list([Head|Front], Back, [Head|Tail]) :-
+	queue_to_list(Front, Back, Tail).

+"""Build definitions for JavaScript binaries compiled with the Closure Compiler.
+
+A single file is produced with the _compiled.js suffix.
+
+By default, the name of the entry point is assumed to be the same as that of the
+build target. This behaviour may be overridden with the "main" attribute.
+
+The optimization level may be set with the "compilation_level" attribute.
+Supported values are: unobfuscated, simple, and advanced.
+
+Example:
