+werc - a minimalist document management system
+----------------------------------------------
+
+Werc is a content management system and web (anti-)framework designed to be simple to
+use, simple to setup, simple to hack on, and not get in the way while allowing
+users easy customization.
+
+For more information see the official website: http://werc.cat-v.org/
+
+
+Installation
+------------
+
+Requirements:
+
+* An http server that can handle CGIs
+* Plan 9 from User Space: http://swtch.com/plan9port,
+	Or 9base-tip: http://tools.suckless.org/9base,
+	Or frontbase: http://openbsd.stanleylieber.com/frontbase
+
+Note: Werc by default expects the Plan 9 tools to be installed under
+/bin/, if you have installed them elsewhere you will need to edit the
+#! line in bin/werc.rc and customize the $plan9port variable in your
+etc/initrc.local.
+
+
+Instructions:
+
+Untar werc at your desired location, configure httpd to use
+/path-to-your-werc-installation/bin/werc.rc as a cgi-script, it is recommended
+that you make werc.rc handle all non-static files (this can be done by setting
+it up as your 404 handler) and setup your virtual hosts to handle static files
+by setting the document root for the domain to
+/path-to-werc-installation/sites/yourdomain.com/, and create a directory for
+your web site under sites/ where you can start adding content right away.
+
+If you will want to allow updates via the web interface (eg., for wiki or
+comments apps) make sure all files under sites/ are writable by the user your
+cgi will run as, usually www-data, for example by doing: chown -R :www-data
+sites/; chmod -R g+w sites/
+
+If your Plan 9 binaries are located somewhere else than the standard /bin/ you
+will need to edit the first line of bin/werc.rc (Note that p9p in particular is
+picky about where it is located, once you run ./INSTALL you should *not* move
+it to a different directory without running ./INSTALL again.)
+
+For general configuration options copy etc/initrc to etc/initrc.local and
+customize it as needed. Site (and directory) specific options can be set in a
+sites/example.com/_werc/config file inside the site's directory. To customize
+templates and included files you can store your own version of the files in
+lib/ under sites/example.com/_werc/lib.
+
+The source tree for the werc website is included under sites/werc.cat-v.org as
+an example, feel free to use it as a template for your own site.
+
+For more details see the documentation section of the website:
+http://werc.cat-v.org/docs/
+
+
+Contact
+-------
+
+For comments, suggestions, bug reports or patches join the werc mailing list
+at: http://werc.cat-v.org or the irc channel #cat-v in irc.freenode.org
+
+If you have a public website that uses werc I would love to hear about it and
+get feedback about you experience setting it up.
+
+Thanks
+------
+
+Garbeam, Kris Maglione, sqweek, soul9, mycroftiv, maht, yiyus, cinap_lenrek,
+khm and many others for their ideas, patches, testing and other contributions.

+The default path for site search is /_search/.  Assuming you want to keep
+that default, you could enable site search like so:
+
+
+mkdir -p /www/werc/sites/MYSITE/_search/_werc/
+echo 'conf_enable_duckduckgo' > /www/werc/sites/MYSITE/_search/_werc/config
+mkdir -p /www/werc/sites/MYSITE/_werc/lib/
+cp /www/werc/apps/duckduckgo/footer.inc.sample /www/werc/sites/MYSITE/_werc/lib/footer.inc
+
+Searches will POST to /_search/ and from there get redirected to Duck Duck 
+Go with a site:$SERVER_NAME prefix.  To have the search path URL be some-
+thing different, you'll have to edit line 23 of app.rc to point to the new
+path.
+
+TODO: 
+* Make it automatically work no matter which directory the app is enabled in.
+* OR make the search path a configuration option.
+* Provide a template for non-footer deployment
+* Enable the search path itself to serve a search form to GET requests

+##########################################################################
+# Title      :  urlencode - encode URL data
+# Author     :  Heiner Steven (heiner.steven@odn.de)
+# Date       :  2000-03-15
+# Requires   :  awk
+# Categories :  File Conversion, WWW, CGI
+# SCCS-Id.   :  @(#) urlencode  1.4 06/10/29
+##########################################################################
+# Description
+#   Encode data according to
+#       RFC 1738: "Uniform Resource Locators (URL)" and
+#       RFC 1866: "Hypertext Markup Language - 2.0" (HTML)
+#
+#   This encoding is used i.e. for the MIME type
+#   "application/x-www-form-urlencoded"
+#
+# Notes
+#    o  The default behaviour is not to encode the line endings. This
+#   may not be what was intended, because the result will be
+#   multiple lines of output (which cannot be used in an URL or a
+#   HTTP "POST" request). If the desired output should be one
+#   line, use the "-l" option.
+#
+#    o  The "-l" option assumes, that the end-of-line is denoted by
+#   the character LF (ASCII 10). This is not true for Windows or
+#   Mac systems, where the end of a line is denoted by the two
+#   characters CR LF (ASCII 13 10).
+#   We use this for symmetry; data processed in the following way:
+#       cat | urlencode -l | urldecode -l
+#   should (and will) result in the original data
+#
+#    o  Large lines (or binary files) will break many AWK
+#       implementations. If you get the message
+#       awk: record `...' too long
+#        record number xxx
+#   consider using GNU AWK (gawk).
+#
+#    o  urlencode will always terminate it's output with an EOL
+#       character
+#
+# Thanks to Stefan Brozinski for pointing out a bug related to non-standard
+# locales.
+#
+# See also

+Blagh - A Blogging engine for people who hate blogs
+===================================================
+
+Blagh is a werc app that implements a blogging engine.
+
+Some features include:
+
+* File based, database free.
+* History browsing.
+* Atom, JSON, and RSS feeds.
+* Server-side feed 'aggregation' (merge multiple blogs into a single one).
+* Comments using [bridge](../bridge/)
+* Markdown formatting.
+
+Possible alternative names: Blag, Blah, Bragg.
+
+Posting
+-------
+
+New pots can be created in at least two different ways: using the web interface (if you have logged in and your user or groups are in `$conf_blog_editors`) or from the command line using the script at `bin/aux/bpst.rc`.  This script will, optionally, take a file as an argument using the `-f` switch.  It will open that file in your `$EDITOR` or create a new temporary file if the `-f` switch is omitted.  When you have finished editing the file, the script will call `ispell` (so you may want to install that as well) to check for spelling errors.  Once that has completed a new directory structure will be created in your blog's root directory as a hidden folder named after the current year (as detected by `date`).  You can inspect this directory structure for continuity and `mv` it to unhide it when you are satisfied.  You are encouraged to read the source of that very simple script, and you shall see that it is trivial to create new posts by simply using `mkdir` and `echo`.
+
+Configuration options
+---------------------
+
+This are options you can set in your _werc/config 
+
+### `conf_enable_blog` *[blog dirs]*
+
+Setup a blog in this dir. By default the blog contents will only include posts stored in this dir, if you pass any arguments the posts in the various dirs will be aggregated in this feed.
+
+Examples:
+
+    # This will setup a blog in this dir that includes only posts in this dir.
+    conf_enable_blog 
+
+    # This will create a blog that aggregates all the posts in all blog dirs in any users/ sub dir.
+    conf_enable_blog users/*/blog 
+
+### `conf_blog_editors`=(*groups or users that will be allowed to make new blog posts*)
+
+This is optional and by default set to the 'blog-editors' group.
+
+### `conf_max_lines_per_post=`*[integer]*
+
+This option may be added using the patch linked bellow.  It defaults to `7` which **should** only include the page heading and the first two paragraphs of each post on the main blogroll(?) page.  This makes many assumptions that should be noted.  It just removes everything from `conf_max_lines_per_post` to the end of the file.  Traditionally, line 1 is the H1 title and line 2 is the line of = required to tell mardown of it's importance.  This then assumes that each paragraph is on a single line, which is not enforced by markdown.  See it in action at <http://blog.senet.us>
+
+[blagh-91a4597480a7-conf\_max\_lines\_per\_post.diff](https://gist.github.com/anjandev/c517e79042148c136b98334867c545d8) (1.2K) (20100114)

+**Author:** A Momi <anjan@momi.ca>

+* Commenting can be handled by [the bridge app](../bridge/).

+Bridge
+======
+
+Bridge is a comments/forum application for werc, which lets people post comments related to any existing document/element.
+
+
+Configuration options
+---------------------
+
+### `conf_enable_comments` [-n] [*users and groups allowed to comment*]
+
+This will enable comments in this directory and all sub-directories. `-n` enables commenting by unregistered users (their posts will be set aside for review and approval by administrators).

+DirDir - A directory-oriented WikiWiki
+======================================
+
+DirDir is the next generation [diri wiki](http://repo.cat-v.org/diri/), now implemented on top of werc and
+taking advantage of its user, site management frameworks and other
+infrastructure.  
+
+Features
+--------
+
+DirDir is still somewhat experimental, but already all features diri had, plus some extras thanks to werc's power:
+
+    * Hierarchical organization.
+    * Markdown formatting.
+    * Easily customizable templates
+    * Simple and fine grained user permisions system.
+    * Completely database free.
+    * All needed to setup diridiri is to set a flag in your _werc/config file.
+    * Automatically wiki-fy existing werc documents.
+    * Implemented in about two dozen lines of rc scripts.
+
+
+Documentation
+-------------
+
+Just login, go to any page, and click the `Edit` button.
+
+To create a new page, go to the address where you want to create the new page, click `Edit`, enter the initial contents, `Save`, and you are done.
+
+
+Status
+------
+
+Mostly usable, all basic features already implemented in the latest werc source
+tree. 
+
+
+TODO
+----
+
+* Do some markdown preprocessing, for example: `[[Foo Bar]]` -> `[Foo Bar](foo-bar)`
+
+
+About the name
+--------------
+
+DirDir is a pun on its predecessor diri and WikiWiki, and [Dirdir is also the title of a novel](http://www.amazon.com/gp/product/0879974788?ie=UTF8&tag=catv-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=0879974788) by science fiction and literature grand master [Jack Vance](http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%2Fs%3Fie%3DUTF8%26redirect%3Dtrue%26search-type%3Dss%26index%3Dbooks%26ref%3Dntt%255Fathr%255Fdp%255Fsr%255F1%26field-author%3DJack%2520Vance&tag=catv-20&linkCode=ur2&camp=1789&creative=39095).

+duckduckgo - Simple sitesearch using DuckDuckGo.com
+===================================
+
+duckduckgo is a very simple app that allows you to redirect a path 
+(by default /_search/) to a query to duckduckgo.com restricted to 
+your site.
+
+Currently, to change that path requires editing the app.  In the
+future, the path will be a configuration option.
+
+Configuration
+-------------
+
+First, create the search path and the _werc directory under it:
+
+	mkdir -p /www/werc/sites/MYSITE/_search/_werc/
+
+Then, enable the duckduckgo app in that directory:
+
+	echo 'conf_enable_duckduckgo' > /www/werc/sites/MYSITE/_search/_werc/config
+
+Next, deploy the search form somewhere on your site.  This example puts
+it in your footer:
+
+	mkdir -p /www/werc/sites/MYSITE/_werc/lib/
+	cp /www/werc/apps/search/footer.inc.sample /www/werc/sites/MYSITE/_werc/lib/footer.inc
+
+Demo
+----
+
+For a demo of this app, see the footer of your favorite cat-v.org site.
+
+TODO
+----
+
+* Make the search path a configuration option
+* Provide a template for non-footer deployment
+* Enable the search path itself to serve a search form to GET requests

+wman - A Web Interface to Man Pages
+===================================
+
+Wman is an app that allows you to export Unix and Plan 9-style man pages. It
+can do this directly, without need to generate static html versions and will
+automatically pick updates and new man pages.
+
+It is also fairly smart in generating links for man page references.
+
+Configuration
+-------------
+
+To display a collection of man pages in a desired path you can use the following config directive:
+
+    conf_enable_wman /usr/share/man
+
+This will allow you to browse the man pages under /usr/share/man.
+
+For man pages organized in the traditional unix structure `manN/foo.N` where N is the section number, set in your config file:
+
+    wman_unix_mode=1
+
+Demo
+----
+
+For a demo of this app see [man.cat-v.org](http://man.cat-v.org).
+
+TODO
+----
+
+* We don't handle compressed man pages, but this should be trivial to add.
+* Unix systems might use different macros for their man pages.
+* Search (using keywords? Google? grep?)
+* Inferno contains man pages named like 'foo-0intro', which are refered as foo-intro(X), should automatically add (or remove) the extra '0' (Examples: sys-intro(2) and draw-intro(2)).

+Development Roadmap
+===================
+
+The versioning scheme is a mess, originally even minor version numbers were
+supposed to be stable and odd ones development branches, but turns out that for
+the most part it is easier to do incremental development instead of keeping
+'dev' and 'stable' branches.
+
+A development branch might be added in the future if the changes are radical
+enough and break backwards compatibility in some important way. For this the
+deprecated and currently outdated `werc-dev` mercurial repo will be used.
+
+
+Werc 1.5.x, current stable branch
+----------
+
+Planned major changes in 1.5
+
+* <strike>Include required p9p binaries in standard distribution (or with some easy to deploy packaging).</strike>
+* New/rewritten css layout, using html5 flexbox [*Done*]
+* File upload support [*Code contributed by maht, needs integration*]
+* OpenID support [*Code contributed by maht, also needs integration*]
+* More complete test suite. [*See: <http://tst.cat-v.org>*]
+* Integrate all changes from 9front live sites [*Done*]
+* Add rc-httpd [*Done*]

+* Add apps/mdir [*Code contributed by khm, needs integration*]
+* Add apps/paste [*Code contributed by khm, rewrite to use apps/upload*]
+
+
+Werc 1.4.x, previous stable branch
+---------------------------------
+
+* Mostly bugfixes, documentation work, and minor improvements.
+
+
+Werc 1.2.x
+----------
+
+* Only security fixes.
+
+
+Werc 1.1.x dev branch
+---------------------
+
+* Convert all templates and pages to HTML 5. [*Done*]
+* Include new markdown implementation in pure awk by yuyis.[*Done*]
+* Native Plan 9 httpd works out of the box. [*Mostly done*]
+* Support for Google's Pubsubhubbub. [*Experimental implementation already done*]
+* Include test suite/site (also to be hosted at http://tst.cat-v.org) [*In Progress*]
+
+
+Werc 1.0.x
+----------
+
+* Abandoned, please upgrade.
+
+
+-----------------------------------------------------
+
+Werc 2.0 Plans
+--------------
+
+* Big redesigns / rewrites.
+* Any non-backwards compatible changes.
+* Bring some sanity to the function/config-variable naming insanity.
+* Nothing else planned yet.

+Plans and Ideas for the Future
+==============================
+
+This page lists various assorted ideas and features that have been proposed at
+some point or another, nothing (except fixing the listed bugs) is assured to be
+implemented, many things here might turn out to be bad ideas.
+
+Features
+--------
+
+* Review ideas from: http://www.w3.org/TR/chips/ and http://www.w3.org/Provider/Style/URI and see if we can do better.
+* Canonize and redirect all requests, we already do this for things like missing or trailing /, should do the same for /. and /./, etc. Deleting trailing . and , should make pasted urls in emails work as links (**Mostly done in RC1**)
+* Blog:
+	* Comment threading.
+	* Some form of pagination (taking advantage of history browsing.) (**Partially done**)
+* Sitemaps:
+	* Index pages should be used for description of directories.
+	* Cache web sitemap generation. (**Done in RC0**)
+* Layout improvements:
+	* Need to find a way to rig the order of items in the sidebar.
+	* Right sidebar.
+    * Top+left/right nav vars (breadcrumbs at the top, current dir listing on the side)
+	* Make it easier to disable all sidebars and headers/footers, eg., for full screen mode.
+	* More testing and optimizations for mobile browsers, eg., http://www.operamini.com/demo/ Left sidebar had some minor issues in cellphones at some point.
+* Better page titles (include whole path hierarchy?) (**Partially done, is it good enough now?**)
+* Allow utf-8 characters in path elements (need to make sure this is safe, and not sure how useful it will be)
+* General code:
+	* Write a regression test suite. (*Started*)
+	* Replace all references to non p9p/p9 programs (*Done?*)
+	* Document better the 'API' for sub-apps, both a set of environment vars apps can rely on (and in some cases set) and functions they can call (WIP).
+* Better generation of descriptive HTML META tags, eg.,: {META name="description" content="This is the Google Summer of Code blog for Plan9 and Inferno projects."} {META name="keywords" content="google, summer of code, inferno, plan9, programming"}
+* Should add werc to certain wikipedia lists:
+	* `http://en.wikipedia.org/wiki/List_of_content_management_systems`
+	* `http://en.wikipedia.org/wiki/Comparison_of_wiki_software`
+* Include txt2tags as builtin alternative to markdown.
+* Spam protection:
+    * Mathematic pseudo-CAPTCHA ala WP's 'Math Comment Spam Protection Plugin'.
+    * kfx (via cinap) suggests you just put a hidden text input box (or textarea?), "Dont write in this input box: [ ..... ]", if the bots fill it out ignore the post
+
+
+
+Future Plans and Blue Sky
+--------------------------
+
+* Wanted [apps](/apps/):
+	* Tagging, eg., append to _werc/tags
+	* Related links sidebar generation.
+	* [Bug/issue tracking app](/apps/gregor/).
+	* Hg/git repository browser.
+	* Implement AtomPub.
+
+* Further modularization and extensibility (meta-templates) (Is the new app framework enough for this?)
+* A way to wrap external cgi applications (eg., existing hg/git browser)
+* A way to generate static sites (ie., use werc as an offline  templating system)
+* [9P](http://9p.cat-v.org) interface.
+* New (simplified) markdown implementation, ideally in C or awk (maybe smu/libsmu by gottox?), yiyus great md2html.awk is a great start!
+  * Simplified
+  * Tables
+  * Images
+  * Autogenerated anchors/navigation boxes
+  * No inline html
+
+Similar frameworks to be investigated and mined for good ideas to steal:
+
+  * TinyTim: http://www.reddit.com/r/programming/duplicates/dbaee/
+  * nanoblogger: http://nanoblogger.sourceforge.net/
+
+
+Known Bugs
+----------
+
+* It seems that certain chars are not propely encoded in cookies, possibly broken chars: :&%[+ Fix should go in cgilib.rc^set_cookie (Have to figure out the proper way to scape cookie strings first)
+* If a dir under apps/ doesn't contain an app.rc file, werc fails to start. A possible fix would be to replace $werc_apps default with `apps/*/app.rc` instead of `apps/*/`, this would be backwards incompatible, but I doubt anyone uses that option.
+* Links in Blagh feeds become confused if markdown 'references' are used, markdown references suck, but I guess we need to address this somehow... 
+* Somewhat similarly to the abouve, relative urls in imgs, links, etc. can easily break when used in Blagh posts, so it is not all markdown's fault.
+* .md files of the following form, without a new line after the last = seem to cause problems in some setups:
+
+    Foo Bar
+    =======
+
+
+
+Fixed or WFM Bugs
+-----------------
+
+* Sitemap can handle $dirfilter inconsistently from other places (**fixed**).
+* Finding directories that are inaccessible (-rx) can generate an infinite loop (**Works for me? Fixed with new menu code?**)
+* Some cat-v.org bits still left over here and there, should make them configurable (1.0 blocker) (**fixed**?)

+Werc Configuration Options
+==========================
+
+You can also find a description of some basic config options in the `etc/initrc` file itself.
+
+General Setup Options
+--------------------
+
+* `formatter` - Command to use for document formatting (usually some form of markdown), should be able to take input both from file names passed as arguments or from stdin if no file names are provided. By default: `formatter=(fltr_cache md2html.awk)`
+
+
+Titles and Metadata
+-------------------
+
+Variables:
+
+* Page title:
+    * siteTitle
+    * siteSubTitle
+
+* Html header meta tags:
+    * meta_description - `<meta name="description" ...`
+    * meta_keywords - `<meta name="keywords" ...`
+    * extraHeaders  - Raw extra html headers, the content of this var will be inserted inside the `<head>` tag..
+
+
+Sidebar and Navigation
+----------------------
+
+Variables:
+
+* sideBarNavTitle
+
+Functions:
+
+* `conf_hide_paths [path_patterns ...]` - Hide the given patterns from navigation menu, sitemap and dir listing (do *not* depend on this for security!).
+
+HTTP Control
+------------
+
+Variables:
+
+* extraHttpHeaders - Raw HTTP headers to be added to response.
+
+Functions:
+
+* `conf_perm_redirect [pattern] destination` - If pattern is provided, match it against the requested url, and replace the match with `destination`; ie., *s/pattern/destination/.
+
+
+Access Control and Permissions
+------------------------------
+
+The permissions system is very flexible, for example to only allow access to members of the group 'editors' you can do something like:
+
+    switch ($req_path) {
+    case /_users/login
+    case /pub/*
+    case /robots.txt
+    case *
+        if(! check_user editors)
+                perm_redirect /_users/login
+    }
+
+
+To automatically redirect users without permission to the login page if they are not members of the group 'editors'.
+
+See also [the documentation on user and group management](user_management).

+Custom CSS Stylesheets
+=====================
+
+If you create a file under your site's dir at _werc/pub/style.css it will be included automatically after the standard werc stylesheet.
+
+You can copy pub/style/style.css and customize it, or you can take a simpler file and just change the main color theme.
+
+Here is an example of how to set the main werc colors:
+
+
+	header nav { background-color: rgb(100,135,220); color: white; }
+	header h1 { background-color: #ff6d06; color: black; }
+	body > nav > div { border-bottom: 1px solid #ddd; } 
+	body > nav > div a { color: rgb(0, 102, 204); } 
+	body > nav > div a:hover { color: white; background-color: rgb(100,135,220); }

+Autogenerated Directory Listings
+================================
+
+If a directory has no `index.md`, `index.html` or `index.txt` and has no other
+*main handler* set up by a [werc app](/apps/), the default directory listing
+handler is used.
+
+The default directory handler simply displays the path to the directory, and a
+list of links to all files and dirs located at this path.
+
+
+Header and footer
+-----------------
+
+If a `_header.md` or `_footer.md` files are found in the directory, their
+contents will be displayed in the corresponding sections before and after
+the directory contents.
+
+
+Tuning the item's order
+------------------------
+
+You can set the `dir_listing_ls_opts` config variable in the dir's corresponding _werc/config to change the way items will be ordered.
+
+For example to list items in reverse chronological order simply add:
+
+    dir_listing_ls_opts=( -t )
+
+The options taken are [the standard Plan 9 ls(1) flags](http://man.cat-v.org/plan_9/1/ls).

+The Rc Template Language
+========================
+
+Implemented by Kris, thanks!
+
+Basic syntax:
+
+* Lines starting with % are executed as rc commands, the resulting output is inserted in the document.
+* use %{ and %} to delimit multi line sections of rc code (note the lack of space between % and { or }!
+* To 'inline' the value of an environment variable use `%($my_var%)`
+
+That is basically it!
+
+For further documentation on rc see:
+
+* [The rc(1) man page from Plan 9](http://man.cat-v.org/plan_9/1/rc).
+* [The rc shell paper by Tom Duff](http://rc.cat-v.org).
+
+
+Examples
+--------
+
+Loops
+
+    <ul>
+    % for(i in a b c) {
+    %   echo '<li>'$i'</li>'
+    % }
+    </uL>
+
+Can also be writen as:
+
+    <ul>
+    %{
+    for(i in a b c) {
+       echo '<li>'$i'</li>'
+    }
+    %}
+    </uL>
+
+and is equivalent to: 
+
+    <ul>
+    % for(i in a b c) {
+    <li>%($i%)</li>
+    % }
+    </uL>

+Site Customization
+==================
+
+To change any of the default templates or include files found in /lib/ simply copy them from /lib/ to your site's _werc/lib/ and edit at will.
+
+To change any of the templates found in /tpl/ (e.g. sitemap.tpl), copy the file to your site's root (e.g. /sites/foo.bar.com/sitemap.tpl) and then edit.
+
+File Types
+----------
+
+* '.tpl' files are rc [template files](rc_template_lang).
+* '.inc' are text files that are inserted 'as is' without any extra processing.
+
+Site Groups
+-----------
+
+Site configuration and customization and be 'grouped' to allow a shared set of templates among a specific group of sites (useful for sets of sub-domains for example).
+
+Simply set 'masterSite' configuration variable to the name of the site you want to 'inherit' templates, style and configuration from.
+
+For example, if we have two sites bar.com and foo.bar.com, and in sites/foo.bar.com/_werc/conf we add:
+
+    masterSite=bar.com
+
+When a template (eg., 404.tpl) is requested it will be looked up first in /sites/foo.bar.com/_werc/lib/404.tpl, if that fails then in /sites/bar.com/_werc/lib/, and if that is missing too, the default /lib/404.tpl is used.
+
+The same applies to .inc files.
+
+
+List of Template and Included Files
+-----------------------------------
+
+Here is a list of the most commonly used templates and include files with their corresponding descriptions.
+
+Include:
+
+* top_bar.inc: The thin header at the top of every page, usually contains static links to other related sites or anything else you like.
+* footer.inc: Similar but at the bottom of every page, by default  includes a link to the user login page.
+* headers.inc: Raw html headers to be included inside <head> tag.
+
+Templates:
+
+* default_master.tpl: This is the main template, which calls all the sidebar and other handlers and applications, usually you won't need to edit it unless you want to make changes to the layout or similar dramatic changes.
+* headers.tpl: Template for the default headers.
+* sitemap.tpl: Template for the sitemap page.
+* 404.tpl: Template for 'File Not Found' pages.
+
+
+See also

+
+* [CSS style sheets customization](css_style).

+User and Group Management
+=========================
+
+User account and group membership information are stored under `etc/users/`.
+
+A user account consists of a directory under `etc/users/` that contains files with that users account information, the only required file is `password` containing a password for the user. For example:
+
+	% ls etc/users/
+	eekee  uriel  yosyp
+	% cat etc/users/uriel/password
+	mypass
+
+Users and groups share the same namespace, you can create a group the same way you create a user but instead of a 'password' file adding a 'members' file containing the names of the group members, one per line.
+
+A 'user-group' directory can contain both a password and members file, in which case it will act concurrently as a user and as a group.
+
+The group 'admin' is 'built-in' and any members in that group will have admin privileges for most werc apps by default.
+
+Example
+-------
+
+To create a user called [glenda](http://glenda.cat-v.org) that is a member of the group `rabbits` you can do:
+
+	% mkdir etc/users/glenda/
+	% echo carrot > etc/users/glenda/password
+	% mkdir -p etc/users/rabbits
+	% echo glenda >> etc/users/rabbits/members
+
+Utils
+-----
+
+The script at bin/aux/addwuser.rc allows you to even more trivially add users. 
+
+	addwuser.rc user_name user_pass [groups ...]

+Setting Up Your HTTP Server to Run Werc
+=======================================
+
+
+Werc should work with any web server that supports the CGI interface, and a few
+that don't. Here are collected instructions and sample configurations for some
+of the most popular HTTP servers that people has used with werc.
+
+In general setup consists of mapping all paths for a virtual host to the
+werc.rc script, usually in practice this means that the `document root` (or
+similar concept) for a virtual host is mapped to
+`/path/to/werc/sites/domain.name.com/`, and if no static file matches the
+request, control is handed to werc.rc, this allows the HTTP server to handle
+static files and werc to handle everything else (note that such a setup will
+expose your `_werc/config` files, which usually should not be a security
+issue).
