#@Disclosure: Needs Scrot for running!
#@ToDo:
# - default output for invalid parameter
# - improve parameter handling
# - improve performance by adjusting the position of the if loops
# - implmentation of $5 for execute a program
# - define 0 as not passed or given, example: xshot foo.jpg 10 2 0 my_game.bin < means that [DIRECTORY] is not or doesn't want to be given

#set variables
NAME=xshot
#$1 Name of the screenshot file
#$2 How often should the screenshots are made
#$3 Delay between the screenshots in seconds
#$4 Where to save
#*NOT IMPLEMENTED* $5 The application name from which the screenshots should be taken
