#
# quick and dirty script to fix permissions for all files and directories under $HOME
# 
# the following is assumed to be true for the final results:
#       * directories: rwxr-x-r-x (octal: 0755)
#       * regular files: rw-r--r-- (octal: 0644)
#       * executable files: rwxr-xr-x (octal: 0755)
#           - Shell scripts (.sh)
#           - Perl files (.pl)
#           - Python files (.py)
#           - Ruby files (.rb)
#           - RUN files (.run)
