+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

+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
