It is responsible for reading the configuration file(s),
processing the command line options and starting the application.
The basic configuration file is 'pyformexrc' located in the pyformex
directory. It should always be present and be left unchanged.
You can copy this file to another location if you want to make changes.
By default, pyformex will try to read the following extra configuration
files (in this order:
default settings: <pyformexdir>/pyformexrc
system-wide settings: /etc/pyformexrc
user settings: $HOME/.pyformex/pyformexrc
local settings $PWD/.pyformexrc
Also, an extra config file can be specified in the command line.
Config file settings always override previous ones.
On exit, the preferences that were changed are written to the last
read config file. Changed settings are those that differ from the settings
in all but the last one.
