+This tactic tries to solve the current goal by a number of standard closing steps.
+In particular, it tries to close the current goal using the closing tactics
+{\tt trivial}, reflexivity, symmetry, contradiction and inversion of hypothesis.
+If this fails, it tries introducing variables and splitting and-hypotheses,
+using the closing tactics afterwards, and splitting the goal using {\tt split} and recursing.
+
+This tactic solves goals that belong to many common classes; in particular, many cases of
+unsatisfiable hypotheses, and simple equality goals are usually solved by this tactic.
