Default configuration
**********************

**pNbody** uses a set of parameters files, color tables and formats files. 
These files are provided by the installation and are by default stored in 
the directory ``site-packages/pNbody/config``.
To display where these files are taken from, you can use the command::

  pNbody_show-path

It is recommanded that the user uses its own configuration files. To be automatically
recongnized by **pNbody**, the latter must be in the user ``~/.pNbody`` directory.
**pNbody** provides a simple command to copy all parameters in this directory. Simply
type::

  pNbody_copy-defaultconfig

and check the values of the new paths::

  pNbody_show-path

You can now freely modify the files contains in the configuratio directory.

By default, the content of the configuration directory is:

+------------------------+------------+--------------------------------------------------------------------------------+
