# README!!!
# To use this script create a new file somewhere on your local file system and paste this code into it. 
# Save the file and navigate to the file's containing directory in your terminal. 
# Begin executing this script by typing whatever you named it at the command line like so:  
# $ ruby GenNewProject
# The script will prompt you for input, upon doing so hit enter to continue running the script.
# If all goes well you should see all the commands execute and finally receive the output "Finished."

# Prerequisites: You must have previously created a subversion repository and made it accessible via the svn:// protocol or HTTP:// or file:/// etc.
