#  Notes: 
#
#  1) Any text that follows a '#' in a file of bash commands (including
#     a bash script) is a comment, and is ignored by the bash interpreter
#
#  2) If you modify this file, you must type
#
#       % source ~/.bashrc
#
#     to have the changes take effect in the current shell.  Also,
#     refer to the 'bash Startup Files' of the Linux / Unix notes at
#     http://bh0.phas.ubc.ca/210/Notes_unix.html#BASHSTARTUP
#     for a discussion of the recommended procedure to follow when
#     changing this file or ~/.profile
