+=head1 DESCRIPTION
+
+B<dbmdeep> is a command line utility which can be used to maintain L<DBM::Deep>
+databases. It is possible to view, modify or delete contents of the database and
+you can export to a L<YAML> file or import from one.
+
+The utility presents an interactive prompt where you enter commands to maintain
+the database, see section B<INTERACTIVE COMMANDS> for more details. Commands can
+also be piped into the tool via STDIN. Example:
+
+ dbmdeep my.db
+ my.db> show
+
+is the same as:
+
+ echo "show" | dbmdeep my.db
+
+=head1 OPTIONS
+
+=over
+
+=item B<--config>
+
+Specify a config file in L<YAML> format. The config may contain special customizations
+for the L<DBM::Deep> instanziation. See section B<CONFIG> for more details.
+
+=item B<--export>
+
+Export the contents of the database to a L<YAML> file. If the specified file name
+is B<->, STDOUT will be used to print the export.
+
+=item B<--import>
+
+Import data from a L<YAML> file. If the database already exists, the contents of
+the import file will be merged with the existing contents, otherwise the database
+will be created.
+
+=item B<--verbose>
+
+Enable debugging output.
+
+=item B<--help>
+
+Print a usage message to STDERR.
+
+=item B<--version>
+
+Print the software version to STDERR.
+
+=back
+
+=head1 CONFIG
+
+A config file is optional. If no config file is specified, B<dbmdeep> makes a couple
+of assumptions about the database: it opens it with the L<DBM::Deep::Storage::File>
+backend with transactions enabled.
+
+Since L<DBM::Deep> allows for a range of options about the storage backend, the B<dbmtree>
+utility supports complete customization using the config file (parameter B<--config>).
+
+Here are couple of examples:
+
+ ---
+ perl: |
+   use Compress::Zlib;
+   %params = (
+       filter_store_key => \&my_compress,
+       filter_store_value => \&my_compress,
+       filter_fetch_key => \&my_decompress,
+       filter_fetch_value => \&my_decompress,
+   );
+   sub my_compress {
+       my $s = shift;
+       utf8::encode($s);
+       return Compress::Zlib::memGzip( $s ) ;
+   }
+   sub my_decompress {
+       my $s = Compress::Zlib::memGunzip( shift ) ;
+       utf8::decode($s);
+       return $s;
+   }
+
+This config implements the sample in L<DBM::Deep::Cookbook#Real-time-Compression-Example>.
+It uses the standard File backend but compresses everything using L<Compress::Zlib>. Note
+that this config only contains one entry: B<perl>, with a multiline value which contains
+perl code. This perl code will be evaluated by B<dbmdeep> at runtime.
+
+Please note, that the hash B<%params> is predefined by B<dbmdeep>, so it must exist and
+must not be local (e.g. don't use: 'my %params'!). The hash may contain anything allowed
+by L<DBM::Deep::new()>.
+
+Also note, that this config doesn't specify a database, so the file name of the database
+must be specified on the command line, eg:
+
+ dbmdeep -c zip.yaml my.db
+
+Another example:
+
+ ---
+ dbi:
+   dsn: dbi:SQLite:dbname=sb.sqlite
+   username:
+   password:
+   connect_args:
+
+Here we use the L<DBM::Deep::Storage::DBI> backend with a sqlite database. You don't need
+to speficy a database file name on the command line in such a case, eg:
+
+ dbmdeep -c sqlite.yaml
+
+Other supported config parameters are: B<editor> which will be used by the interactive
+B<edit> command and B<more> which will be used by interactive commands which display
+large amounts of data.
+
+=head1 INTERACTIVE COMMANDS
+
+=head2 DISPLAY COMMANDS
+
+=over
+
+=item B<list>
+
+Lists the keys of the current level of the database hash.
+
+Shortcut: B<l>.
+
+=item B<show>
+
+Does nearly the same as B<list> but also shows the content of the
+keys. If a key points to a structure (like a hash or an array), B<show>
+whill not display anything of it, but instead indicate, that there'e
+more behind that key.
+
+Shortcut: B<sh>.
+
+=item B<dump>
+
+Dumps out everything of the current level of the database hash.
+
+Shortcut: B<d>.
+
+=item B<get> key | /regex>
+
+Displays the value of B<key>. If you specify a regex, the values of
+all matching keys will be shown.
+
+=back
+
+=head2 NAVIGATION COMMANDS
+
+=over
+
+=item B<enter> key
+
+You can use this command to enter a sub hash of the current hash.
+It works like browsing a directory structure. You can only enter
+keys which point to sub hashes.
+
+Shortcuts: B<cd>
+
+If the key you want to enter doesn't collide with a command, then
+you can also just directly enter the key without 'enter' or 'cd' in
+front of it, eg:
+
+ my.db> list
+ subhash
+ my.db> subhash
+ my.db subhash> dump
+ my.db subhash> ..
+ my.db>^D
+
+If you specify B<..> as parameter (or as its own command like in the
+example below), you go one level up and leave the current sub hash.
+
+=back
+
+=head2 EDIT COMMANDS
+
+=over
+
+=item B<set> key value
+
+Use the B<set> command to add a new key or to modify the value
+of a key. B<value> may be a valid perl structure, which you can
+use to create sub hashes or arrays. Example:
+
+ my.db> set users [ { name => 'max'}, { name => 'joe' } ]
+ ok
+ mydb> get users
+ users =>
+ {
+   'name' => 'max'
+ },
+ {
+   'name' => 'joe'
+ }
+
+B<Please note that the B<set> command overwrites existing values
+without asking>.
+
+=item B<edit> key
+
+You can edit a whole structure pointed at by B<key> with the
+B<edit> command. It opens an editor with the structure converted
+to L<YAML>. Modify whatever you wish, save, and the structure will
+be saved to the database.
+
+=item B<append> key value
+
+This command can be used to append a value to an array. As with the
+B<set> command, B<value> can be any valid perl structure.
+
+=item B<drop> key
+
+Delete a key.
+
+Again, note that all commands are executed without further asking
+or warning!
+
+=item B<pop> key
+
+Remove the last element of the array pointed at by B<key>.
+
+=item B<shift> key
+
+Remove the first element of the array pointed at by B<key>.
+
+=back
+
+=head2 TRANSACTION COMMANDS
+
+See L<DBM::Deep#TRANSACTIONS>.
+
+=over
+
+=item B<begin>
+
+Start a transaction.
+
+=item B<commit>
+
+Save all changes made since the transaction began to the database.
+
+=item B<rollback>
+
+Discard all changes of the transaction.
+
+=back
+
+=head2 MISC COMMANDS
+
+=over
+
+=item B<help>
+
+Display a short command help.
+
+Shortcuts: B<h> or B<?>.
+
+=item B<CTRL-D>
+
+Quit B<dbmdeep>
+
+Shortcuts: B<quit>.
