libextractor is a simple library for meta-data extraction.
libextractor uses a plugin-mechanism that makes it easy to add support
for more file formats, allowing anybody to add new extractors quickly.
libextractor currently features meta-data extractors for HTML, PDF, PS,
MP3, OGG, JPEG, GIF, PNG, TIFF, RPM, ZIP, REAL, RIFF (AVI), MPEG, QT
and ASF. It also detects many more MIME-types in a fashion similar to
the well-known "file" tool. Furthermore, a generic extractor that
extracts dictionary words from binaries is included. Supported
dictionaries are currently da, en, de, it and no.
