This is operating system or shell dependent. I believe the limitation
is more the length of the command line in characters than it is the
length in tokens.
http://support.microsoft.com/default.aspx?scid=kb;en-us;830473 for
Windows, >300 for Unix but can be tweaked by the admin.

If the length of arguments is getting a bit long, you may want to
consider providing switches (Getopt::Std or Getopt::Long) or enclosing
the parameter in quote characters so a long string becomes one argument.
