+.SH DESCRIPTION
+.PP
+gnunet\-directory lists the contents of one or more GNUnet directories. A
GNUnet directory is a binary file that contains a list of GNUnet file\-sharing
URIs and meta data. The names of the directory files must be passed as
command\-line arguments to gnunet\-directory.

+.SH NOTES
+A GNUnet directory is a file containing a list of GNUnet URIs and meta data.
The keys can point to files, other directories or files in namespaces. In
other words, a GNUnet directory is similar to UNIX directories. The difference
to tar and zip is that GNUnet directory does not contain the actual files
(except if they are really small, in which case they may be inlined), just
symbolic (links), similar to directories with symbolic links in UNIX
filesystems. The benefit is that the individual files can be retrieved
separately (if desired) and if some of the files are inserted to another node
in GNUnet, this just increases their availability but does not produce useless
duplicates (for example, it is a better idea to publish a collection of
pictures or compressed sound files using a GNUnet directory instead of
processing them with archivers such as tar or zip first). Directories can
contain arbitrary meta data for each file.
+
+If a directory has missing blocks (for example, some blocks failed to
download), GNUnet is typically able to retrieve information about other files
in the directory. Files in a GNUnet directory have no particular order; the
GNUnet code that generates a directory can reorder the entries in order to
better fit the information about files into blocks of 32k. Respecting 32k
boundaries where possible makes it easier for gnunet\-directory (and other
tools) to recover information from partially downloaded directory files.
+
+At the moment, directories can be created by \fBgnunet\-gtk\fP and
\fBgnunet\-publish\fP. Just like ordinary files, a directory can be published
in a namespace.
+
+GNUnet directories use the (unregistered) mimetype
\fBapplication/gnunet\-directory\fP. They can show up among normal search
results. The directory file can be downloaded to disk by
\fBgnunet\-download\fP(1) for later processing or be handled more directly by
\fBgnunet\-gtk\fP(1).
