libiptcdata is a library, written in C, for manipulating the International
Press Telecommunications Council (IPTC) metadata stored within multimedia
files such as images. This metadata can include captions and keywords,
often used by popular photo management applications. The library provides
routines for parsing, viewing, modifying, and saving this metadata. The
library is licensed under the GNU Library General Public License (GNU LGPL).

The libiptcdata package also includes a command-line utility, iptc, for
editing IPTC data in JPEG files.

Python bindings are included by default but can be turned off by invoking
script with PY_BINDINGS=no
