### AUTOMAGIC ###
$BaseName = "counter4";
# counter or counterbanner or counterfiglet
#
# Outputs the number of times a specific page has been accessed.
# The output depends on which page 'called' it, and what the program
# is named:
#
# The counter can "take arguments" via its name. That is, if you tack
# -arg to the end of the program name, -arg is taken to be an argument.
# For example, if you call the counter 'counter-ord', '-ord' is considered
# an argument, and an ordinal count (1st, 2nd, 3rd, ...) will be printed
# instead of (1, 2, 3, ...). Note that counterord does the same thing as
# counter-ord for backward compatibility.
#
# Currently recognized arguments:
#
# -f=font sets "font" to be the font for figlet
# -lang=lang sets the language used to ordinalize to "lang"
# -nc no count; don't to write the incremented count back to the file
# -nl no link; don't automatically generate a link
# -nd no display; don't display anything, just count
# -ord make an ordinal count instead of regular
# -doc=document override the DOCUMENT_URI environment variable
#
# Example: counterfiglet-ord-f=bigfont-nc
#
# This will cause the counter to call figlet as the output routine, printing
# in a big font an ordinal count, without updating the access count file.
# Note that the order of arguments is irrelevant so long as you spell the
# file name correctly. It is generally assumed that the ability to take
# different arguments/use different output routines is done with symlinks:
# i.e. ln -s counter counterfiglet-ord-f=bigfont-nc
