<para>
An alternative to <varname>path</varname> which
provides a format string referring to tag values.
Every time a new song starts or a new tag gets
received from a radio station, a new file is
opened. If the format does not render a file
name, nothing is recorded.
</para>
<para>
A tag name enclosed in percent signs ('%') is
replaced with the tag value. Example:
<parameter>~/.mpd/recorder/%artist% -
%title%.ogg</parameter>
</para>
<para>
Square brackets can be used to group a substring.
If none of the tags referred in the group can be
found, the whole group is omitted. Example:
<parameter>[~/.mpd/recorder/[%artist% -
]%title%.ogg]</parameter> (this omits the dash
when no artist tag exists; if title also doesn't
exist, no file is written)
</para>
<para>
The operators "|" (logical "or") and "&amp;"
(logical "and") can be used to select portions of
the format string depending on the existing tag
values. Example:
<parameter>~/.mpd/recorder/[%title|%name%].ogg</parameter>
(use the "name" tag if no title exists)
