.SH NAME
.nf
w_diff \-  Compare two NIST SPHERE header waveform files
.fi

.SH SYNOPSIS
.nf
\fBw_diff\fP w_diff [-hvdws] [-cCSTR] file1 file2
.fi

.SH DESCRIPTION

W_diff is a waveform comparing program.  It can compare the SPHERE
headers of two files as well as the data portions of two SPHERE files.
If the files do not differ, a zero is returned by the program, otherwise
a non-zero value is returned.

.TP 8
.B "\-cCSTR"
Convert the files by the 'CSTR' used in a call to 
sp_set_data_mode()
.TP 8
.B "\-d"
Compare the data portions of the files byte by byte.
.TP 8
.B "\-h"
Print this help message.
.TP 8
.B "\-s"
Compare the SPHERE headers of the files.
.TP 8
.B "\-w"
Compare the waveforms of the two files after converting them
using the conversion string in 'CSTR'.  This is the default
.TP 8
.B "\-v"
Set the verbosity level up by one, repeat the v for higher levels.  A
verbosity setting of 1 will provide a description of each tests
outcome.
