# Program: b - backup files passed as arguments or current directory without args
#    Desc: Backup a File in ../.backup dir w/timestamp.
#   Notes: You should use git or another source code control system instead
#          but this program is for when you need a quick file backup
#          instead of manually backing up the file with cp continuously.
