(synopsis "Library to extract meta-data from media files")
(description
"GNU Libextractor is a library used to extract meta data from files.
The goal is to provide developers of file-sharing networks, browsers or
WWW-indexing bots with a universal library to obtain simple keywords and
meta data to match against queries and to show to users instead of only
relying on filenames. libextractor contains the shell command extract that,
similar to the well-known file command, can extract meta data from a file
and print the results to stdout.
Currently, libextractor supports the following formats: HTML, MAN, PS, DVI,
OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), FLAC,
MP3 (ID3v1 and ID3v2), OGG, WAV, S3M (Scream Tracker 3), XM (eXtended Module),
IT (Impulse Tracker), NSF(E) (NES music), SID (C64 music), EXIV2, JPEG, GIF,
PNG, TIFF, DEB, RPM, TAR(.GZ), LZH, LHA, RAR, ZIP, CAB, 7-ZIP, AR, MTREE,
PAX, CPIO, ISO9660, SHAR, RAW, XAR FLV, REAL, RIFF (AVI), MPEG, QT and ASF.
Also, various additional MIME types are detected.")
