# Name : Gravel
# Type : Oligomorphic Python worm
# Author: Mike_Hood
# Description: Gravel searches for python files in the current directory, analyzes their
# code and create a list of all lines that must be executed and that are not
# simple comments or commands wich modify the flow of the program. Using this
# list the worm simply writes its lines in specific areas of the victim's code
# so that neither Gravel's code nor victim's code get corrupted.
# Thanks to: WarGame, girls and music.
