| <title>age</title> |
| <para>The date field, when set, is used to |
| decide what files to delete when cleaning. If |
| a file or directory is older than the current |
| time minus the age field it is deleted. The |
| field format is a series of integers each |
| followed by one of the following |
| postfixes for the respective time units:</para> |
| |
| <variablelist> |
| <varlistentry> |
| <term><varname>s</varname></term> |
| <term><varname>min</varname></term> |
| <term><varname>h</varname></term> |
| <term><varname>d</varname></term> |
| <term><varname>w</varname></term> |
| <term><varname>ms</varname></term> |
| <term><varname>m</varname></term> |
| <term><varname>us</varname></term></varlistentry> |
| </variablelist> |
| |
| <para>If multiple integers and units are specified the time values are summed up.</para> |
| |
| <para>The age field only applies to lines starting with d, D and x. If ommited or set to - no automatic clean-up is done.</para> |
