-.PP
-\&\fBarename.pl\fR currently supports two widely used audio formats, namely
-\&\s-1MPEG\s0 Layer3 and ogg vorbis. The format, that \fBarename.pl\fR will assume
-for each input file is determined by the file's filename-extension
-(\fI.mp3\fR vs. \fI.ogg\fR). The extension check is case\-insensitive.
-.PP
-By default, \fBarename.pl\fR will refuse to overwrite destination files,

-\&\fBarename.pl\fR uses up to two configuration files. As for most programs,
-the script will try to read a configuration file, that is located in the

-The format of the aforementioned files is pretty simple.
-It is parsed line by line. Empty lines, lines only containing whitespace
-and lines, whose first non whitespace character is a hash character (\fI#\fR)
-are ignored.
-.PP
-Each line consists of one or two parts. If there are two parts,
-they are separated by whitespace. The first part of the line will be used
-as the identifier of a setting (eg. \fIverbose\fR). The second part (read: the
-rest of the line) is used as the value of the setting. (No quoting, or whatsoever
-is required.)

-
-B<arename.pl>'s templates are quite simple, yet powerful.
-
-At simplest, a template is just a fixes character string. However, that would
-not be exactly useful. So, the script is able to expand certain expressions
-with information gathered from the file's tagging information.
-
-The expressions can have two slightly different forms:
-
-=over 8
-
-=item B<&>I<identifier>
-
-The simple form.
-
-=item B<&>I<identifier>B<[>I<length>B<]>
-
-The "complex" form. The I<length> argument in square brackets defines the
-maximum length, to which the expression should be expanded.
-
-=back
-
-=head2 Available expression identifiers
-
-The data, that is expanded is derived from tagging information in
-the audio files. For I<.ogg> files, the tag checking B<arename.pl> does
-is case insensitive and the first matching tag will be used.
-
-=over 8
-
-=item B<album>
-
-Guess.
-
-=item B<artist>
-
-Guess again.
-
-=item B<compilation>
-
-For I<.ogg> this is filled with information found in the 'albumartist' tag.
-For I<.mp3> this is filled with information from the id3v2 TPE2 frame.
-If the mp3 file only provides a id3v1 tag, this is not supported.
-
-=item B<tracknumber>
-
-The number of the position of the track on the disc. Obviously. However, this
-can be in the form of '12' or '12/23'. In the second form, only the part left
-of the slash is used. The tracknumber is a little special, as you can defined
-to what width it should be padded with zeros on the left (see I<tnpad> setting
-in L<arename(1)/SETTINGS>).
