 +======Synopsis:​======
 +$__center__(<​width>​ <​text>​)
 +
 +======Technical:​======
 +This function returns the input text right-justified in a buffer that is
 +precisely (** ((width - strlen(text)) / 2) + strlen(text)** ) characters
 +wide.  The width must be given, there is no default.
 +
 +======Practical:​======
 +This function returns the given text, padded on the left such that it
 +will appear to be "​centered"​ in the width given. ​ The right side is not
 +padded, only the left.  To force padding on both sides, you must use the
 +width qualifier $[]var.
 +
 +======Returns:​======
 +Input text centered in given width.
 +
 +======Examples:​======
 +<​file>​
 +$center(15 hello there) ​              ​returns " ​ hello there"
 +$[15]center(15 hello there) ​          ​returns " ​ hello there  "
 +</​file>​
