Description:
parser library for RSS and Atom feeds
Syndication is a parser library for RSS and Atom feeds. It offers a unified, format-agnostic view on the parsed feed, so that the using application does not need to distinguish between feed formats. . This package is part of the KDE Development Platform PIM libraries module.
