-  \section sec_what What is the purpose of QOAuth?
-
-  The main motivation to create this library was to provide an interface to OAuth
-  protocol for (Qt-based) C++ applications in an easy way. This is very early version
-  of the library, and it lacks some functionality, but in the same time it is capable
-  of sending OAuth authorization requests as well as preparing requests for accessing
-  User's Protected Resources.
-
-  \section sec_lic License and Authors
-
-  The project is licensed under <a href=http://www.gnu.org/licenses/lgpl-2.1.html>GNU LGPL
-  license</a> version 2.1 or later. The work is done by Dominik Kapusta (d at ayoy dot net).
-
-  \section sec_inst How to install?
-
-  \subsection ssec_deps Dependencies
-
-  There are a few things necessary to get OAuth library working:
-
-  <ol>
-    <li>Qt libraries, version 4.4 or higher,</li>
-    <li>QCA (Qt Cryptographic Architecture), available from
-        <a href=http://delta.affinix.com/qca>Delta XMPP Project</a>, version 2.0.0
-        or higher,</li>
-    <li>OpenSSL plugin to QCA (qca-ossl), available from QCA page, and requiring OpenSSL.</li>
-  </ol>
-
-  \b Note: KDE4 users meet all the requirements out of the box.
-
-  \subsection ssec_inst Installation
-
-  The source code repository is hosted on <a href=http://github.com/ayoy/qoauth>GitHub</a>
-  and the code can be checked out from there easily using git:
-  \verbatim
-    $ git clone git://github.com/ayoy/qoauth.git \endverbatim
-
-  To compile the code, follow the simple procedure:
-
-  \verbatim
-    $ qmake
-    $ make
-    $ sudo make install \endverbatim
-
-  \subsection ssec_use Usage
-
-  Configuring your project to work with QOAuth library is extremely simple. Firstly,
-  append a line to your project file:
-  \verbatim
-    CONFIG += oauth \endverbatim
-
-  Then include the following header in your code:
-  \verbatim
-    #include <QtOAuth> \endverbatim
-
-  \b Note: This follows the Qt scheme, i.e. <tt>QT += xml ==> #include <QtXml></tt>, etc.
-
-  \section sec_bugs Bugs and issues
-
-  Please file all the bug reports to the QOAuth bug tracking system at
-  <a href="http://ayoy.lighthouseapp.com/projects/32547-qoauth/tickets?q=all">
-  lighthouseapp.com</a>. If you wish to contribute, you're extremely welcome
-  to fork a <a href=http://github.com/ayoy/qoauth>GitHub</a> repository and
-  add your input there.

-  \class QOAuth::Interface interface.h <QtOAuth>
-  \brief This class provides means for interaction with network services supporting
-         OAuth authorization scheme.
-
-  The QOAuth::Interface class is meant to enable OAuth support in applications in as simple way
-  as possible. It provides 4 basic methods, two of which serve for authorization purposes:
-    \li \ref requestToken(),
-    \li \ref accessToken(),
-
-  and the other two help with creation of requests for accessing Protected Resources:
-    \li \ref createParametersString(),
-    \li \ref inlineParameters().
-
-  \section sec_auth_scheme OAuth authorization scheme
-
-  According to <a href=http://oauth.net/core/1.0/#consumer_req_param>
-  OAuth 1.0 Core specification</a>, <em>the OAuth protocol enables websites or applications
-  (Consumers) to access Protected Resources from a web service (Service Provider) via an
-  API, without requiring Users to disclose their Service Provider credentials to the
-  Consumers</em>. Simply, OAuth is a way of connecting an application to the Service
-  Provider's API without needing to provide User's login or password. The authorization
-  is based on an exchange of a Token (user-specific) together with a Consumer Key
-  (application-specific), encrypted with a combination of so called Token Secret and
-  Customer Secret. Getting access to Protected Resources consists in three basic steps:
-  <ol>
-    <li>obtaining an unauthorized Request Token from the Service Provider,</li>
-    <li>asking the User to authorize the Request Token,</li>
-    <li>exchanging the Request Token for the Access Token.</li>
-  </ol>
-  Details are covered in <a href=http://oauth.net/core/1.0/#anchor9>Section 6</a> of the
-  OAuth 1.0 Core Specification. As the authorization procedure is quite complex, the QOAuth
-  library helps to simplify it by doing all the dirty work behind the scenes.
-
-  \section sec_req_token OAuth authorization with QOAuth
-
-  First step of OAuth authorization can be done in one line using QOAuth library.
-  Consult the example:
-
-  \include requestToken.cpp
-
-  Once the unauthorized Request Token is received, User has to authorize it using
-  Service Provider-defined method. This is beyond the scope of this library. Once User
-  authorizes the Request Token, it can be exchanged for an Access Token that authorizes the
-  application to access User's Protected Resources. This can be done with another one line:
-
-  \include accessToken.cpp
-
-  Once the Access Token is received, the application is authorized.
-
-  \section sec_acc_res Requesting Protected Resources with QOAuth
-
-  In order to access Protected Resources, the application has to send a request containing
-  arguments including Customer Key and Access Token, and encrypt them with Customer Secret
-  and Token Secret. The process of constructing such a request can be reduced to another
-  one-line call with QOAuth::Interface. The example code for inlining all request parameters
-  (both User-specific and OAuth-related):
-
-  \include getResources.cpp
-
-  If Service Provider requires the OAuth authorization to be done in the <tt>Authorization</tt>
-  header field, then only User-specific parameters should be inlined with the URL:
-
-  \include getResources2.cpp
-
-  \section sec_capabilities Capabilities
-
-  QOAuth library works with all 3 signature methods supported by the OAuth protocol, namely
-  HMAC-SHA1, RSA-SHA1 and PLAINTEXT. Hovewer, RSA-SHA1 and (especially) PLAINTEXT
-  methods may still need additional testing for various input conditions.
