+$SCRIPT
+Toby Vincent <tobyv13@gmail.com>
+
+$SCRIPT is a script for managing and navigating a persistent temp directory. In
+order to function properly, this script must be sourced in the currently shell.
+Consider setting an alias such as
+
+    alias td=". $SCRIPT"
+
+USAGE:
+    $SCRIPT [OPTIONS] <COMMAND>
+    $SCRIPT [OPTIONS]
+
+OPTIONS:
+    -h, --help      Display this message
+    -f, --force     Use the --force argument when removing TD
+
+ARGS:
+    toggle (default)
+        Switch between TD_ORIGIN and TD. This will create TD if it does not
+        exist. This is the default if no command is provided.
+
+    new | create      
+        Creates a new temp directory and cds into it it stores the path
+        to the temp directory in TD, and the path to the previous directory in 
+        TD_ORIGIN.
+
+    rm | remove
+        Removes the directory stored in TD unsets TD and TD_ORIGIN.
+
+    ls | list | show
+        Shows the current values for TD and TD_ORIGIN
