+Javascript docstrings
+=====================
+
+Whereas in Python source code we only need to include a module docstrings 
+using the directive `.. automodule:: mypythonmodule`, we will have to 
+explicitely define Javascript modules and functions in the doctrings since
+there is no native directive to include Javascript files.
+
+Rest generation
+---------------
+
+`pyjsrest` is a small utility parsing Javascript doctrings and generating the
+corresponding Restructured file used by Sphinx to generate HTML documentation.
+This script will have the following structure::
+
+  ===========
+  filename.js
+  ===========
+  .. module:: filename.js
+
+We use the `.. module::` directive to register a javascript library
+as a Python module for Sphinx. This provides an entry in the module index.
+
+The contents of the docstring found in the javascript file will be added as is
+following the module declaration. No treatment will be done on the doctring.
+All the documentation structure will be in the docstrings and will comply
+with the following rules.
+
+Docstring structure
+-------------------
+
+Basically we document javascript with RestructuredText docstring
+following the same convention as documenting Python code.
+
+The doctring in Javascript files must be contained in standard 
+Javascript comment signs, starting with `/**` and ending with `*/`,
+such as::
+
+ /**
+  * My comment starts here.
+  * This is the second line prefixed with a `*`.
+  * ...
+  * ...
+  * All the follwing line will be prefixed with a `*` followed by a space.
+  * ...
+  * ...
+  */ 
+
+
+Comments line prefixed by `//` will be ignored. They are reserved for source
+code comments dedicated to developers.
+
+
+Javscript functions docstring
+-----------------------------
+
+By default, the `function` directive describes a module-level function.
+
+`function` directive
+~~~~~~~~~~~~~~~~~~~~
+
+Its purpose is to define the function prototype such as::
+
+    .. function:: loadxhtml(url, data, reqtype, mode) 
+
+If any namespace is used, we should add it in the prototype for now, 
+until we define an appropriate directive.
+::
+    .. function:: jQuery.fn.loadxhtml(url, data, reqtype, mode) 
+
+Function parameters
+~~~~~~~~~~~~~~~~~~~
+
+We will define function parameters as a bulleted list, where the
+parameter name will be backquoted and followed by its description.
+
+Example of a javascript function docstring::
+
+    .. function:: loadxhtml(url, data, reqtype, mode) 
+
+    cubicweb loadxhtml plugin to make jquery handle xhtml response
+
+    fetches `url` and replaces this's content with the result
+
+    Its arguments are:
+
+    * `url`
+
+    * `mode`, how the replacement should be done (default is 'replace')
+       Possible values are :
+           - 'replace' to replace the node's content with the generated HTML
+           - 'swap' to replace the node itself with the generated HTML
+           - 'append' to append the generated HTML to the node's content
+
+
+Optional parameter specification
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Javascript functions handle arguments not listed in the function signature.
+In the javascript code, they will be flagged using `/* ... */`. In the docstring,
+we flag those optional arguments the same way we would define it in
+Python::
+
+    .. function:: asyncRemoteExec(fname, arg1=None, arg2=None)
+

+=========================================
+Refactoring the CSSs with UI properties
+=========================================
+
+Overview
+=========
+
+Managing styles progressively became difficult in CubicWeb. The
+introduction of uiprops is an attempt to fix this problem.
+
+The goal is to make it possible to use variables in our CSSs.
+
+These variables are defined or computed in the uiprops.py python file
+and inserted in the CSS using the Python string interpolation syntax.
+
+A quick example, put in ``uiprops.py``::
+
+  defaultBgColor = '#eee'
+
+and in your css::
+
+  body { background-color: %(defaultBgColor)s; }
+
+
+The good practices are:
+
+- define a variable in uiprops to avoid repetitions in the CSS
+  (colors, borders, fonts, etc.)
+
+- define a variable in uiprops when you need to compute values
+  (compute a color palette, etc.)
+
+The algorithm implemented in CubicWeb is the following:
+
+- read uiprops file while walk up the chain of cube dependencies: if
+  cube myblog depends on cube comment, the variables defined in myblog
+  will have precedence over the ones in comment
+
+- replace the %(varname)s in all the CSSs of all the cubes
+
+Keep in mind that the browser will then interpret the CSSs and apply
+the standard cascading mechanism.
+
+FAQ
+====
+
+- How do I keep the old style?
+
+  Put ``STYLESHEET = [data('cubicweb.old.css')]`` in your uiprops.py
+  file and think about something else.
+
+- What are the changes in cubicweb.css?
+
+  Version 3.9.0 of cubicweb changed the following in the default html
+  markup and css:
+
+  ===============  ==================================
+   old              new
+  ===============  ==================================
+   .navcol          #navColumnLeft, #navColumnRight
+   #contentcol      #contentColumn
+   .footer          #footer
+   .logo	    #logo
+   .simpleMessage   .loginMessage
+   .appMsg	    (styles are removed from css)
+   .searchMessage   (styles are removed from css)
+  ===============  ==================================
+
+  Introduction of the new cubicweb.reset.css based on Eric Meyer's
+  reset css.
+
+  Lots of margin, padding, etc.
