+	echo "
+	Used for hiding/unhiding programs to acheive quake-dropdown-like-functionality. Can create a dropdown window if one does not already exist and provides options to control the intial size and position, e.g. to leave panels visible. When used with a terminal, provides the option to specify the name of a tmuxinator or tmux session to automatically start or attach to.
+
+	Also supports the ability to auto-hide and auto-show. For example, this can be used to automatically hide a window when opening something, e.g. image viewer, video player, etc. from it, and then re-show the window whenever the image view, video player, etc. is closed.
+
+	Takes a terminal as an argument or one of auto_show, auto_hide, or toggle_auto_hide. 'toggle_auto_hide' toggles whether calling 'auto_hide' or 'auto_show' will have any effect.
+
+usage: tdrop [options] <program> or <auto_show/auto_hide/toggle_auto_hide>
+options:
+	-h height    specify a height for a newly created term (default: 100%)
+	-w width     specify a width for a newly created term (default: 45%)
+	-x pos       specify x offset for a newly created term (default: 0)
+	-y pos       specify y offset for a newly created term (default: 1)
+	-s name      name for tmux or tmuxinator session (if not given, will not use tmux)
+	-n num       num or extra text; only needed if want multiple dropdowns of same program (default: "")
+	-p cmd       provide a pre command to float the window if necessary
+	-P cmd       provide a post command to float the window if necessary
+	-W           the given program is not a terminal (or lacks an -e flag) (default: assume it IS terminal)
+	--no-cancel  don't cancel auto-showing
+	             (default is to prevent this when manually toggling a term after it is auto-hidden)
+	--help       print help
+
+See man page for more details.
