    constraint: Port to the new docs format
    
     - Drop the "SECTION".
     - Add attributes annotations for properties and getter methods.
     - Remove excessive linking and redundant types

  *
  * `GtkConstraint` describes a constraint between an attribute on a widget
  * and another attribute on another widget, expressed as a linear equation.
  *
- * For instance:
+ * The typical equation for a constraint is:
  *
  * ```
- *   target.attr1 = source.attr2 × multiplier + constant
+ *   target.target_attr = source.source_attr × multiplier + constant
  * ```
