 ============================================
 Overview of the IPython configuration system
 ============================================
 
 This section describes the IPython configuration system. This is based on
 :mod:`traitlets.config`; see that documentation for more information
 about the overall architecture.
 
 Configuration file location
 ===========================
 
 So where should you put your configuration files? IPython uses "profiles" for
 configuration, and by default, all profiles will be stored in the so called
 "IPython directory". The location of this directory is determined by the
 following algorithm:
 
 * If the ``ipython-dir`` command line flag is given, its value is used.
 
 * If not, the value returned by :func:`IPython.paths.get_ipython_dir`
   is used. This function will first look at the :envvar:`IPYTHONDIR`
   environment variable and then default to :file:`~/.ipython`.
   Historical support for the :envvar:`IPYTHON_DIR` environment variable will
   be removed in a future release.
 
 For most users, the configuration directory will be :file:`~/.ipython`.
 
 Previous versions of IPython on Linux would use the XDG config directory,
 creating :file:`~/.config/ipython` by default. We have decided to go
 back to :file:`~/.ipython` for consistency among systems. IPython will
 issue a warning if it finds the XDG location, and will move it to the new
 location if there isn't already a directory there.
 
 Once the location of the IPython directory has been determined, you need to know
 which profile you are using. For users with a single configuration, this will
-simply be 'default', and will be located in 
+simply be 'default', and will be located in
 :file:`<IPYTHONDIR>/profile_default`.
 
 The next thing you need to know is what to call your configuration file. The
 basic idea is that each application has its own default configuration filename.
 The default named used by the :command:`ipython` command line program is
 :file:`ipython_config.py`, and *all* IPython applications will use this file.
 The IPython kernel will load its own config file *after*
 :file:`ipython_config.py`. To load a particular configuration file instead of
 the default, the name can be overridden by the ``config_file`` command line
 flag.
 
 To generate the default configuration files, do::
 
     $ ipython profile create
 
 and you will have a default :file:`ipython_config.py` in your IPython directory
 under :file:`profile_default`.
+
 .. note::
 
     IPython configuration options are case sensitive, and IPython cannot
     catch misnamed keys or invalid values.
     
     By default IPython will also ignore any invalid configuration files. 
 
 .. versionadded:: 5.0
 
     IPython can be configured to abort in case of invalid configuration file.
     To do so set the environment variable ``IPYTHON_SUPPRESS_CONFIG_ERRORS`` to
     `'1'` or `'true'`
 
 
 Locating these files
 --------------------
 
 From the command-line, you can quickly locate the IPYTHONDIR or a specific
 profile with:
 
 .. sourcecode:: bash
 
     $ ipython locate
     /home/you/.ipython
     
     $ ipython locate profile foo
     /home/you/.ipython/profile_foo
 
 These map to the utility functions: :func:`IPython.utils.path.get_ipython_dir`
 and :func:`IPython.utils.path.locate_profile` respectively.

 Profiles
 ========
 
 A profile is a directory containing configuration and runtime files, such as
 logs, connection info for the parallel apps, and your IPython command history.
 
 The idea is that users often want to maintain a set of configuration files for
 different purposes: one for doing numerical computing with NumPy and SciPy and
 another for doing symbolic computing with SymPy. Profiles make it easy to keep a
 separate configuration files, logs, and histories for each of these purposes.
 
 Let's start by showing how a profile is used:
 
 .. code-block:: bash
 
     $ ipython --profile=sympy
 
 This tells the :command:`ipython` command line program to get its configuration
 from the "sympy" profile. The file names for various profiles do not change. The
 only difference is that profiles are named in a special way. In the case above,
 the "sympy" profile means looking for :file:`ipython_config.py` in :file:`<IPYTHONDIR>/profile_sympy`.
 
 The general pattern is this: simply create a new profile with:
 
 .. code-block:: bash
 
     $ ipython profile create <name>
 
 which adds a directory called ``profile_<name>`` to your IPython directory. Then
 you can load this profile by adding ``--profile=<name>`` to your command line
 options. Profiles are supported by all IPython applications.
 
 IPython ships with some sample profiles in :file:`IPython/config/profile`. If
 you create profiles with the name of one of our shipped profiles, these config
 files will be copied over instead of starting with the automatically generated
 config files.
 
 IPython extends the config loader for Python files so that you can inherit
 config from another profile. To do this, use a line like this in your Python
 config file:
 
 .. sourcecode:: python
 
     load_subconfig('ipython_config.py', profile='default')
