msgcomm \- match two message catalogs
.SH SYNOPSIS
.B msgcomm

.SH DESCRIPTION
.\" Add any additional description here
.PP
Find messages which are common to two or more of the specified PO files.
By using the \fB\-\-more\-than\fR option, greater commonality may be requested
before messages are printed.  Conversely, the \fB\-\-less\-than\fR option may be
used to specify less commonality before messages are printed (i.e.
\fB\-\-less\-than\fR=\fI\,2\/\fR will only print the unique messages).  Translations,
comments and extracted comments will be preserved, but only from the first
PO file to define them.  File positions from all PO files will be
cumulated.
