+This forces any currently selected region to be automatically
+resized at least a certain @var{width} and @var{height}. All
+other surrounding regions will be resized in order to accomodate.
+This constraint follows everytime the @code{focus} command is
+used. The @code{resize} command can be used to increase either
+dimension of a region, but never below what is set with
+@code{focusminsize}. The underscore @samp{_} is a synonym for
+@code{max}. Setting a @var{width} and @var{height} of @code{0 0}
+(zero zero) will undo any constraints and allow for manual resizing.
+Without any parameters, the minimum width and height is shown.
