#
#  Makes sure that if any application instance is
#  currently running, it switches to new theme.

## Theme setter
#
#  Takes care of permanently writing the desired

## Theme includer
#
#  Makes sure that theme is actually included in
#  default application startup routine.
#  This is the most invasive step of theming since it

## Dependency Checker

#  Makes sure the processor is called for the correct
