+=head1 NAME
+
+Fuse::DBI - mount your database as filesystem and use it
+
+=head1 SYNOPSIS
+
+ use Fuse::DBI;
+ Fuse::DBI->run( ... );
+
+See L<run> below for examples how to set parametars.
+
+=head1 DESCRIPTION
+
+This module will use L<Fuse> module, part of C<FUSE (Filesystem in USErspace)>
+available at L<http://sourceforge.net/projects/avf> to mount
+your database as file system.
+
+That will give you posibility to use normal file-system tools (cat, grep, vi)
+to manipulate data in database.
+
+It's actually opposite of Oracle's intention to put everything into database.
+
+
