# Syntax : ./generate.pl agents_number [floor_number]
|
|
# agents_number : can specify a number ranging from 2 to 500 ( upgradable by upgrading database ). number of visitors and residents are evenly splitted.
|
|
# floor_number : number of floor in building ( not counting floor 0 ), ranging from 1 to whatever number is too big for perl. By default, number of floor is 25.
|
|
# the scripts will generate two files : visitors.txt and residents.txt
|
|
# visitors.txt syntax : each line is : visitor_name;resident_name\n
|
|
# residents.txt syntax : each line is : resident_name;resident_floor;destination_floor\n
|
|
# resident_floor is ranging from 1 to floor_number ( implying residents cant live at floor 0 ), while destination_floor is ranging from 0 to floor_number
