#  Displays Structure of Directory Hierarchy          #
#  -------------------------------------------------  #
#  This tiny script uses "ls", "grep", and "sed"      #
#  in a single command to show the nesting of         #
#  sub-directories.  The setup command for PATH       #
#  works with the Bash shell (the Mac OS X default).  #
#                                                     #
#  Setup:                                             #
#     $ cd ~/apps/tree                                #
#     $ chmod u+x tree.sh                             #
#     $ ln -s ~/apps/tree/tree.sh ~/bin/tree          #
#     $ echo "PATH=~/bin:\${PATH}" >> ~/.profile      #
#                                                     #
#  Usage:                                             #
#     $ tree [directory]                              #
#                                                     #
#  Examples:                                          #
#     $ tree                                          #
#     $ tree /etc/opt                                 #
#     $ tree ..                                       #
