##############################################################
## This program takes a string as input (a password) and    ##
##  permutes the password.				    				##
##############################################################
# How to use: ./programName.py [password_string]            ##
# Example: ./transform.py ABCabc123!!!                      ##
# Note: Ensure the #!/location/to/python is correct		    ## 
# Note: Make sure to chmod a+x [filename] on your system 	## 
# Note: Some characters such as the ' and ; interact with   ##
# the shell and don't permute properly.	 Passing it in as   ##
# a file containing the password makes it perform better    ##
