[doc] migrate documentation to sphinx using sphinx-apidoc and including README

The rationnal to do this migration are:

* be able to host the documentation on readthedocs.org, right now, according to
  the README, the user needs to built it locally to be able to read it
* epydoc is not maintained anymore
* sphinx generally offer a better user experience and allow to write real
  documentation instead of just generating an API
* it was quick to do with sphinx-apidoc and seems worth it to be able to put it
  online

+.. logilab common documentation master file, created by
+   sphinx-quickstart on Thu May 23 03:36:04 2019.
+   You can adapt this file completely to your liking, but it should at least
+   contain the root `toctree` directive.
+
+Welcome to logilab common's documentation!
+==========================================
+
+Logilab common's is a bunch of modules providing low level functionnalities
+shared among some python projects devel by Logilab.
+
+What's this ?
+-------------
+
+This package contains some modules used by different Logilab projects.
+
+It is released under the GNU Lesser General Public License.
+
+There is no documentation available yet but the source code should be clean and
+well documented.
+
+Designed to ease:
+
+* handling command line options and configuration files
+* writing interactive command line tools
+* manipulation of files and character strings
+* manipulation of common structures such as graph, tree, and pattern such as visitor
+* generating text and HTML reports
+* more...
+
+
+Installation
+------------
+
+Extract the tarball, jump into the created directory and run ::
+
+    python setup.py install
+
+For installation options, see ::
+
+    python setup.py install --help
+
+
+Provided modules
+----------------
+
+Here is a brief description of the available modules.
+
+Modules providing high-level features
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* :ref:`cache <cache>`, a cache implementation with a least recently used algorithm.
+
+* :ref:`changelog <changelog>`, a tiny library to manipulate our simplified ChangeLog file format.
+
+* :ref:`clcommands <clcommands>`, high-level classes to define command line programs handling
+  different subcommands. It is based on `configuration` to get easy command line
+  / configuration file handling.
+
+* :ref:`configuration <configuration>`, some classes to handle unified configuration from both
+  command line (using optparse) and configuration file (using ConfigParser).
+
+* :ref:`proc <proc>`, interface to Linux /proc.
+
+* :ref:`umessage <umessage>`, unicode email support.
+
+* :ref:`ureports <ureports>`, micro-reports, a way to create simple reports using python objects
+  without care of the final formatting. ReST and html formatters are provided.
+
+
+Modules providing low-level functions and structures
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* :ref:`compat <compat>`, provides a transparent compatibility layer between different python
+  versions.
+
+* :ref:`date <date>`, a set of date manipulation functions.
+
+* :ref:`daemon <daemon>`, a daemon function and mix-in class to properly start an Unix daemon
+  process.
+
+* :ref:`decorators <decorators>`, function decorators such as cached, timed...
+
+* :ref:`deprecation <deprecation>`, decorator, metaclass & all to mark functions / classes as
+  deprecated or moved
+
+* :ref:`fileutils <fileutils>`, some file / file path manipulation utilities.
+
+* :ref:`graph <graph>`, graph manipulations functions such as cycle detection, bases for dot
+  file generation.
+
+* :ref:`modutils <modutils>`, python module manipulation functions.
+
+* :ref:`shellutils <shellutils>`, some powerful shell like functions to replace shell scripts with
+  python scripts.
+
+* :ref:`tasksqueue <tasksqueue>`, a prioritized tasks queue implementation.
+
+* :ref:`textutils <textutils>`, some text manipulation functions (ansi colorization, line wrapping,
+  rest support...).
+
+* :ref:`tree <tree>`, base class to represent tree structure, and some others to make it
+  works with the visitor implementation (see below).
+
+* :ref:`visitor <visitor>`, a generic visitor pattern implementation.
+
+
+Modules extending some standard modules
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* :ref:`debugger <debugger>`,  `pdb` customization.
+
+* :ref:`logging_ext <logging_ext>`, extensions to `logging` module such as a colorized formatter
+  and an easier initialization function.
+
+* :ref:`optik_ext <optik_ext>`, defines some new option types (regexp, csv, color, date, etc.)
+  for `optik` / `optparse`
+
+
+Modules extending some external modules
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* :ref:`sphinx_ext <sphinx_ext>`, Sphinx_ plugin defining a `autodocstring` directive.
+
+* :ref:`vcgutils <vcgutils>` , utilities functions to generate file readable with Georg Sander's
+  vcg tool (Visualization of Compiler Graphs).
+
+
+To be deprecated modules
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Those `logilab.common` modules will much probably be deprecated in future
+versions:
+
+* `testlib`: use `unittest2`_ instead
+* `interface`: use `zope.interface`_ if you really want this
+* `table`, `xmlutils`: is that used?
+* `sphinxutils`: we won't go that way imo (i == syt)
