+
+# Instructions:
+#
+# - Go to root directory of a Ruby on Rails project
+# - Enter the following in Bash Terminal `bash launch_dev.sh`, which creates a new
+#   Terminal tab that executes the Rails server, and after 10 seconds it opens a
+#   second new Terminal tab that runs the `open http://localhost:3000` command to
+#   open the website of the Rails server in your web browser (after waiting 10 seconds
+#   to ensure the Rails Server has fully loaded)
+
+# About:
+# 
+# Shell function to setup Developer Environment with command
+# `bash launch_dev.sh` using osascript command to execute custom
+# AppleScript code that instructs the Terminal app to
+# open multiple new Terminal.app tabs automatically, naming the tabs,
+# and attaching them to Terminal Multiplexer (tmux) Sessions,
+# by simulating the keypress of CMD+T
+# and running a script with chained commands that set the
+# new Terminal tab's title. The $COMMAND variable is also
+# evaluated and executed in both new tabs. Output from original
+# call to osascript is redirected to /dev/null
