strigi-utils binary package in Ubuntu Xenial i386

 This package is part of Strigi Desktop Search, it contains utilities powered
 by Strigi:
  * deepfind, an enhanced version of find. It lists files embedded in other
    files like .deb, .rpm, .tar.gz, email attachments, and other files.
  * deepgrep, an enhanced version of grep. It searches in binary files like
    OpenOffice files, mp3s, Microsoft office files, pdfs and also in files
    embedded in other files like .deb, .rpm, .tar.gz, email attachments, pdf
    and other files.
  * xmlindexer, a program that outputs the file parsing results as xml.
    It walks through a directory and outputs an XML file containing all
    the metadata and text it can extract from the files it encounters.
    This means that the Strigi's powers of data extraction are now available
    to all applications that can parse XML simply by calling xmlindexer and
    parsing the output.
 .
 See the 'strigi-daemon' package for more information.
