.SH NAME
formulacheck \- check a boolean formula
.SH SYNOPSIS
.B formulacheck
[\fIOPTION\fR]... [\fIINFILE\fR]
.SH DESCRIPTION
Checks whether the boolean formula (an mCRL2 data expression of sort Bool) in 
INFILE holds. If INFILE is not present, stdin is used.
.SH OPTIONS
.TP
\fIOPTION\fR can be any of the following:
.TP
\fB-c\fR, \fB--counter-example\fR
display a valuation for which the formula does not hold, in case it is neither 
a contradiction nor a tautology
.TP
\fB-o\fR, \fB--induction\fR
apply induction on lists
.TP
\fB-p\fR\fIPREFIX\fR, \fB--print-dot\fR=\fIPREFIX\fR
save a \&.dot file of the resulting BDD if it is impossible to determine whether 
the formula is a contradiction or a tautology; PREFIX will be used as prefix of 
the output files
.TP
\fB-r\fR\fINAME\fR, \fB--rewriter\fR=\fINAME\fR
use rewrite strategy NAME:
  \&'jitty\&' for jitty rewriting (default),
  \&'jittyc\&' for compiled jitty rewriting,
  \&'jittyp\&' for jitty rewriting with prover

.TP
\fB-z\fR\fISOLVER\fR, \fB--smt-solver\fR=\fISOLVER\fR
use SOLVER to remove inconsistent paths from the internally used BDDs (by 
default, no path elimination is applied):
  \&'cvc\&' for the SMT solver CVC3
.TP
\fB-s\fR\fISPECFILE\fR, \fB--spec\fR=\fISPECFILE\fR
check the formula against the data types from the LPS or PBES in SPECFILE
.TP
\fB-t\fR\fILIMIT\fR, \fB--time-limit\fR=\fILIMIT\fR
spend at most LIMIT seconds on proving a single formula
.TP
\fB--timings\fR[=\fIFILE\fR]
append timing measurements to FILE\&. Measurements are written to standard error 
if no FILE is provided
.TP
\fB-w\fR, \fB--witness\fR
display a valuation for which the formula holds, in case it is neither a 
contradiction nor a tautology
.TP
Standard options:
.TP
\fB-q\fR, \fB--quiet\fR
do not display warning messages
.TP
\fB-v\fR, \fB--verbose\fR
display short intermediate messages
.TP
\fB-d\fR, \fB--debug\fR
display detailed intermediate messages
.TP
\fB--log-level\fR=\fILEVEL\fR
display intermediate messages up to and including level
.TP
\fB-h\fR, \fB--help\fR
display help information
.TP
\fB--version\fR
display version information
