+<longdescription lang='en'>
+E is a theorem prover for full first-order logic with equality. It
+accepts a problem specification, typically consisting of a number of
+first-order clauses or formulas, and a conjecture, again either in
+clausal or full first-order form. The system will then try to find a
+formal proof for the conjecture, assuming the axioms.
+
+If a proof is found, the system can provide a detailed list of proof
+steps that can be individually verified. If the conjecture is
+existential (i.e. it’s of the form “there exists an X with property
+P”), the latest versions can also provide possible answers (values for
+X).
+
+Development of E started as part of the E-SETHEO project at TUM. The
+first public release was in in 1998, and the system has been
+continuously improved ever since. I believe that E now is one of the
+most powerful and friendly reasoning systems for first-order
+logic. The prover has successfully participated in many competitions.
