4. What is the Bootstrap
In computer science, the term bootstrap refers to starting
a system.
In ProdigyView, the Bootstrap is used to configure the
system and load the necessary data and files before
execution.
In addition to several ways of booting the system, there
are numerous configurations that can be passed to the
bootstrap to customize it.
In many of the examples, if you look at the top of file you
will notice that the system is booted before any code is
executed.

6. _BootCompleteSystem
The file _BootCompleteSystem.php is the automatic
configuration when booting the entire system. This
includes setting the database, loading plugins, loading the
libraries, etc.

7. _BootSystemMinusPlugins
This boot options completely boots the entire system but
does not load any plug-ins.

8. _BootSystemMinusDatabase
This boot configuration will boot the system but will not
connect or set any database options. This means that
database dependent features such as plug-ins will also
not be booted. Unless a database is set at a different
point in time, you will also not have access too other
database coupled features such as:
 CMS
 Applications
 MVC Initializer

9. Custom Bootstrap – Class
Loader
The previous boot options provided by ProdigyView are
very basic. Adding a more complex bootstrap
configuration can be accomplished easily. Start by using
the _classLoader. The _classLoader will enable the usage
of all the core libraries.

10. Custom Bootstrap - Options
Next we have to configure the options that are passed
into the PVBoostrap::bootSystem() method. These
options control which classes are initialized. A complete
list of configuration options is available in the API.

11. Boostrap Config Option
The most important function in the bootstrap is the config
options array.
The variables in the array are passed to the init functions of
various other classes.

Config Array
PVLibraries::init PVTemplate::init PVSession::init PVSecurity::init PVRouter::init

12. Challenge!
If you are new to ProdigyView and also new to programming, this
challenge may be a little more difficult than the others.
Go into the code of the file ‘core/system/PVSession.php’ init
method. Modify the variables in the config section of the
bootstrap in a way that it will affect your cookies.
