+.Sh DESCRIPTION
+In order to share files with other GNUnet users, the files must first be made available to GNUnet.
+GNUnet does not automatically share all files from a certain directory (however, you can do this with the gnunet\-auto\-share tool).
 In fact, even files that are downloaded are not automatically shared.
-.PP
-In order to start sharing files, the files must be added either using
-gnunet\-publish or a graphical interface such as gnunet\-fs\-gtk.
-The command line tool gnunet\-publish is more useful if many files are
-supposed to be added.
-gnunet\-publish can automatically publish batches of files,
-recursively publish directories, create directories that can be
-browsed within GNUnet and publish file lists in a namespace.
-When run on a directory, gnunet\-publish will always recursively
-publish all of the files in the directory.
-.PP
-gnunet\-publish can automatically extract keywords from the files that
-are shared.
-Users that want to download files from GNUnet use keywords to search
-for the appropriate content.

+gnunet\-publish can automatically extract keywords from the files that are shared.
+Users that want to download files from GNUnet use keywords to search for the appropriate content.
 You can disable keyword extraction with the \-D option.
 You can manually add keywords using the \-k option.
 The keywords are case\-sensitive.
-.PP
-In addition to searching for files by keyword, GNUnet allows
-organizing files into directories.
-With directories, the user only needs to find the directory in order
-to be able to download any of the files listed in the directory.

 Directories can contain pointers to other directories.

+With gnunet\-publish, it is easy to create new directories simultaneously when adding the files.
 Simply pass the name of a directory instead of a file.
-.PP
-Since keywords can be spammed (any user can add any content under any
-keyword), GNUnet supports namespaces.
-A namespace is a subset of the searchspace into which only the holder
-of a certain pseudonym can add content.
-Any GNUnet user can create any number of pseudonyms using
-\fBgnunet\-pseudonym\fR.  Pseudonyms are stored in the user's GNUnet
-directory.
-While pseudonyms are locally identified with an arbitrary string that
-the user selects when the pseudonym is created, the namespace is
-globally known only under the hash of the public key of the pseudonym.
-Since only the owner of the pseudonym can add content to the
-namespace, it is impossible for other users to pollute the namespace.
-gnunet\-publish automatically publishes the top\-directory (or the
-only file if only one file is specified) into the namespace if a
-pseudonym is specified.
-.PP
-It is possible to update content in GNUnet if that content was placed
-and obtained from a particular namespace.
-Updates are only possible for content in namespaces since this is the
-only way to assure that a malicious party can not supply counterfeited
-updates.
-Note that an update with GNUnet does not make the old content
-unavailable, GNUnet merely allows the publisher to point users to more
-recent versions.
-You can use the \-N option to specify the future identifier of an
-update.
-When using this option, a GNUnet client that finds the current (\-t)
-identifier will automatically begin a search for the update (\-N)
-identifier.
-If you later publish an update under the (\-N) identifier, both
-results will be given to the user.
-.PP
-You can use automatic meta\-data extraction (based on libextractor) or
-the command\-line option \-m to specify meta-data.

+You can use automatic meta\-data extraction (based on libextractor) or the command\-line option \-m to specify meta-data.
 For the \-m option you need to use the form keyword\-type:value.
-For example, use "\-m os:Linux" to specify that the operating system
-is Linux.
-Common meta\-data types are "author", "title" , "mimetype",
-"filename", "language", "subject" and "keywords".
-A full list can be obtained from the extract tool using the option
-\-\-list.
-The meta\-data is used to help users in searching for files on the
-network.

+.Pp
 GNUnet supports two styles of publishing files on the network.
-Publishing a file means that a copy of the file is made in the local
-(!) database of the node.
-Indexing a file means that an index is added to the local (!)
-database with symbolic links to the file itself.
-The links will use the SHA-512 hash of the entire file as the
-filename.
-Indexing is generally significantly more efficient and the default
-choice.
-However, indexing only works if the indexed file can be read (using
-the same absolute path) by gnunet-service-fs.
-If this is not the case, indexing will fail (and gnunet\-publish will
-automatically revert to publishing instead).
-Regardless of which method is used to publish the file, the file will
-be slowly (depending on how often it is requested and on how much
-bandwidth is available) dispersed into the network.
-If you publish or index a file and then leave the network, it will
-almost always NOT be available anymore.
-.PP

-This will allow other users to download the file as fast as possible,

-If you set it to 1 (default), you use the standard anonymous routing
-algorithm (which does not explicitly leak your identity).
-However, a powerful adversary may still be able to perform traffic
-analysis (statistics) to over time infer data about your identity.
-You can gain better privacy by specifying a higher level of anonymity,
-which increases the amount of cover traffic your own traffic will get,
-at the expense of performance.
-Note that regardless of the anonymity level you choose, peers that
-cache content in the network always use anonymity level 1.

+.Pp
 The definition of the ANONYMITY LEVEL is the following.
 0 means no anonymity is required.
-Otherwise a value of 'v' means that 1 out of v bytes of "anonymous"
-traffic can be from the local user, leaving 'v-1' bytes of cover
-traffic per byte on the wire.
-Thus, if GNUnet routes n bytes of messages from foreign peers (using
-anonymous routing), it may originate n/(v-1) bytes of data in the same
-time\-period.
-The time\-period is twice the average delay that GNUnet defers
-forwarded queries.
