       tag    (not implemented anymore)

       cat (grep)
              output  the  lines  of  the  full  package  tag  database  that match the given tag
              expression. A tag expression (given as a single argument) is an arbitrarily complex
              binary  expression  of  tag  names. For example: role::program && ((use::editing ||
              use::viewing) && !works-with::text)

       check  Check that all the tags in the given tagged  collection  are  present  in  the  tag
              vocabulary. Checks the main database if no file is specified

       diff (mkpatch)
              Create  a  tag  patch  between  the  current  tag  database  and the tag collection
              [filename]. Standard input is used if filename is not specified

       search (dumpavail)
              Output the packages matching the given tag expression

       show   (deprecated) mostly the same as apt-cache show <pkgnames>

       submit (no longer supported) see for patch submit.

       tagcat Output the tag vocabulary

              Show the vocabulary information about a tag

              Show a summary of all tags whose data contains the given strings

       update Updates the package tag database (requires root) Collect package tag data from  apt
              cache,  regenerate  the  debtags tag database and main index. It needs to be run as

              Filter out the tags that are not found in the given vocabulary file debtags manages
              package tag data in a debian system and performs basic queries on it.

       debtags  can be used to perform basic queries on the Debtags system: the vocabulary can be
       queried with the tagshow and tagsearch commands; a package tag  database  can  be  checked
       against  the  vocabulary  with  the  check  command; the whole collection can be copied to
       standard output to be processed with tagcoll or other tools by the cat  command;  packages
       can  be  searched by tags using the grep command. Finally, tags can be listed with tag ls,
       edited with the tag add and tag rm, and submitted to the Debtags database with submit.

       The   update   command   can   be   used   to   download   extra   tags   as   listed   in
       /etc/debtags/sources.list: see the contents of that file for more information.


              The normative tag vocabulary

              The  system  package  tags database, only kept as an easily parsable reference.  In
              the same directory there is a the binary index  with  the  same  content,  used  by
              applications for fast access.

              The list of sources to build the package tags database from


       Here are some example invocations of debtags:

         # Update the package tag database
         debtags update

         # Show apt-cache information about the mutt package,
         # adding tag information
         debtags show mutt

         # Search the tag vocabulary for mail-related tags
         debtags tagsearch mail

         # Output a list of all packages which can edit raster images, excluding
         # shared libraries and dummy packages
         debtags search "use::editing && works-with::image:raster && \
                       ! (role::shared-lib || role::dummy)"

         # Show all mail clients
         debtags search 'works-with::mail && network::client'

         # Output the collection of all mail clients, ready to be reprocessed via
         # tagcoll
         debtags grep 'works-with::mail && network::client'

         # Produce an easily navigable hierarchy with the collection data
         debtags cat | tagcoll hierarchy

         # Produce a local tag patch
         debtags cat > work-tags
         ...edit work-tags...
         debtags diff work-tags > my-tagpatch

         # Submit the patch
         debtags submit my-tagpatch

         # Edit the tags of a package (the patch will be stored in ~/.debtags/patch)
         # then send your changes
         debtags tag add debtags implemented-in::c++ interface::commandline
         debtags tag rm debtags devel::buildtools
         debtags submit
