Remove `path' functionality from centos-art.sh script.
- Instead, functionalities that relay on path information to do
their works (e.g., help) need to implement their own way to
copy, delete and rename files related to them.
- Later, higher functionalities will call specific functionalities
to realize the file movement inside the repository, as well as
any path transformation that can be realized on higher
functionalities to avoide unnecessary use of file movement
actions inside specific functionalities.
- This configuration is required because specific functionalities
work with specific information that can't be set on higher
functionalities. This is, because they are very specific to one
functionality.
