# Files from Alexander Todorovic
|
||||
|
||||
This folder contains work done by Alexander Todorovic, from the scripting team.
|
||||
Due to abscence of whatsoever communication with Marco Conterno, the scripting
|
||||
team team leader, these pages overlap with some of the content created by the
|
||||
team members that volunteered to help the scripting team. These pages are also
|
||||
not coded in Jekyll. For these reasons, everything in this folder is not in the
|
||||
website and is kept just for grading purposes.
