.SH NAME
.P
pecomato \- a portable picture\-embedded metadata processor

.SH SYNOPSIS
.P
\fBpecomato\fR [\fIOPTION\fR...] \fIOP\fR [\fIEXPR\fR] \fIFILE\fR [\fIFILE\fR...]

.P
\fBpecomato\fR [\fIOPTION\fR...] \fIOP\fR [\fIEXPR\fR] \fI@FILE\fR

.P
usage of form \fIOP\fR \fIEXPR\fR only concerns \fIOP\fR mode \fBdump\-value\fR, see below.

.P
use \fI@file\fR to read a list of files from that file. the file must contain exactly one
filename to process per line (don't escape anything, filenames are taken as\-is).

.SH DESCRIPTION
.P
\fBpecomato\fR is basically designed to display any kind of information embedded
in picture files, as well as checking, filtering, extracting, removing, adding
and fixing such information. In other words, it's a metadata processor.

.P
It supports the following file formats: \fIJPEG/JFIF\fR, \fIAdobe PSD\fR and \fIFFO\fR, raw \fIIPTC\fR.
And it knows about the following metadata formats: \fIJFIF\fR, \fIIPTC\fR, \fIExif\fR, \fIAdobe\fR and
Fotostation. More file and metadata formats might be supported later: \fITIFF\fR,
etc.

.P
One of its main goals is to check the validity of parsed metadata as well as
optionally check the strict compliance to official standards. On another hand,
it aims to provide ways of fixing broken or not compliant chunks as well as
providing general basic functions to manipulate the metadata.

fix metadata inconsistencies when possible

.P
\fBextracting options:\fR

.TP
 \fB\-x\fR, \fB\-\-extract\fR \fITYPE\fR
extract and save metadata to a standalone file (see
below for a list of metadata types that can be extracted)
.TP
 \fB\-t\fR, \fB\-\-ext\fR \fIEXTENSION\fR

metadata that is extracted (default: \fI.iptc\fR)
.TP
 \fB\-a\fR, \fB\-\-append\-ext\fR

the extracted metadata (default: replace original file
extension)

.P
\fBfiltering options:\fR

.TP
 \fB\-i\fR, \fB\-\-include\fR \fIEXPR\fR
a filter expression describing the datasets to keep
.TP
 \fB\-i\fR, \fB\-\-include\fR \fI@FILE\fR
