#  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

# Set the path which will be used to locate executables.  
# Note the inclusion of # the following directories:
#
#   .            ->  Current working directory.
#   ~/bin        -> 'bin' directory in your home directory, convenient
#                    and standard place to put your own executables 
#                    (scripts, programs, etc.)
#   ~phys210/bin -> 'bin' directory in phys210's home directory (course 
#                    account). From time to time, executables that you 
#                    might want/need to use may be placed here by the 
#                    instructor
#
# Also note the use of the '\' (backslash) character in the assignment 
# of PATH to "continue" a long command across one or more lines.  
# This is a standard mechanism for line continuation in bash and 
# other shells.  
#
# WARNING!!  When you use this mechanism, ensure that NOTHING follows 
# the '\', including white space, or you will generally induce an error
# that can be difficult to debug!  In addition, the continuation lines
# should always begin in the first column to avoid introducing unwanted
# whitespace in the command.
