++.SH NAME
++clasp \- a conflict-driven nogood learning answer set solver 
++.SH SYNOPSIS
++.B clasp
++[\fInumber\fR] \fR[\fIoptions\fR]
++.SH DESCRIPTION
++This manual page documents briefly the
++.B clasp
++command.
++.PP
++.\" TeX users may be more comfortable with the \fB<whatever>\fP and
++.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
++.\" respectively.
++\fBclasp\fP is an answer set solver for (extended) normal logic
++programs. It combines the high-level modeling capacities of answer set
++programming (ASP) with state-of-the-art techniques from the area of
++Boolean constraint solving. The primary clasp algorithm relies on
++conflict-driven nogood learning, a technique that proved very
++successful for satisfiability checking (SAT). Unlike other learning
++ASP solvers, clasp does not rely on legacy software, such as a SAT
++solver or any other existing ASP solver. Rather, clasp has been
++genuinely developed for answer set solving based on conflict-driven
++nogood learning. clasp can be applied as an ASP solver (on LPARSE
++output format), as a SAT solver (on simplified DIMACS/CNF format), or
++as a PB solver (on OPB format).
++.SH OPTIONS
++These programs follow the usual GNU command line syntax, with long
++options starting with two dashes (`-').
++A summary of options is included below.
