You are missing the echo in the else branch.
On top, a function will always have a complete set of parameters of its own, so, in your case, usage will always have zero parameters, regardless of how many parameters your script has gotten. Do input error testing in the body of the script, then call respective error handlers/functions.

mensis

MENSIS(1)						      General Commands Manual							 MENSIS(1)

NAME

       mensis - To or for, by with or from TrueType tables

SYNOPSIS

       mensis  [-cmap  maptype]  [-depth  pixeld]  [-display str] [-help] [-keyboard ktype] [-nosplash [-script file] [-sync [-usage] [-vc vclass]
       [-version] fontfile ...

DESCRIPTION

       The program mensis allows you to examine and modify some of the tables in a truetype or opentype font.

       If the argument list contains a font file name (or several), pfaedit opens a table view window for each font displaying all the	tables	in
       that  font  In the absence of options or arguments, the program opens a file-picker window, allowing you to browse your disk to find a font
       file.

       This manual page is intended only as a rudimentary overview; see  the  HTML  Users  Manual  for	more  complete	information.   http://men-
       sis.sourceforge.net/

OPTIONS

       -cmap maptype
	      Employ the specified method to control 8-bit colormaps, where maptype assumes one of these three values:

	      current
		     Attempt to allocate colors in the current (shared) colormap.  The program will likely not find everything it requires.

	      copy   Allocate what can be allocated, then copy the current colormap; it can thus make use of cells other programs are using.

	      private
		     Create a new colormap and fill it with the required colors.

       -depth pixeld
	      Attempt to employ a visual that matches the specified pixel depth, pixeld.

       -display str
	      Employ the X display specified by the string str (for example: localhost:0).

       -help  Display the usage description and start a web client displaying the online documentation.

       -keyboard ktype
	      Alter the displayed menus to employ modifier keys appropriate to the specified keyboard type, where ktype assumes one of the follow-
	      ing four values:

	      ibm    IBM PC type keyboard.

	      mac    Apple Macintosh keyboard.

	      sun    Sun workstation keyboard.

	      ppc    Macintosh keyboard, but on a system running SuSe linux (the mappings differ from those used under MacOS X).

       -nosplash
	      Suppress display of the splash screen.

       -script file
	      Execute the script named file.  Does not open the X display.  This must be the first argument passed to mensis. Any other  arguments
	      are  handled  by the scriptfile itself.  Any other command line arguments will be passed to the script.  The program contains a com-
	      mand interpreter which allows access to most but not all of its interactive features.  If a scriptfile is  executable,  and  if  its
	      first  line  contains the string "mensis", then the argument -script may be omitted. This means that mensis can be used as an inter-
	      preter.

       -sync  Make X synchronous.  Used primarily for debugging, this option slows X down.

       -usage Display the usage description.

       -vc vclass
	      Attempt to use a visual that matches the class, vclass, specified as either the name of a visual class or an integer  enumerating  a
	      visual class.

       -version
	      Display the current version (a six digit string containing the date stamp of the source files).

ENVIRONMENT

       If any of the following environment variables exist, they are used:

       BROWSER
	      Specifies the name of a browser program for examining documentation.

       MENSIS_VERBOSE
	      Turns on verbose mode in scripting. Each statement is printed as it is executed.

FILES

       /usr/local/share/mensis/*.ui
	      translations for the user interface

       /usr/local/share/doc/mensis/*.html
	      optional location for online documentation.
