 Tactics sometimes have to generate new names for hypothesis. Letting
 the system decide a name with the {\tt intro} tactic is not so good
 since it is very awkward to retrieve the name the system gave.

+This tactic applies to any goal.  The argument {\term} is a term
+well-formed in the local context and the argument {\ident} is an
+hypothesis of the context.  The tactic {\tt apply {\term} in {\ident}}
+tries to match the conclusion of the type of {\ident} against a non
+dependent premisses of the type of {\term}, trying them from right to
+left.  If it succeeds, the statement of hypothesis {\ident} is
+replaced by the conclusion of the type of {\ident}. The tactic also
+returns as many subgoals as the number of other non dependent premises
+in the type of {\term} and of the non dependent premises of the type
+of {\ident}.  The tactic {\tt apply} relies on first-order
+pattern-matching with dependent types.
