config directive controls various aspects of the file parsing. There
are two valid tags:
errmsgcontrols what message is sent back to the client if an error includes while parsing the document. When an error occurs, it is logged in the server's error log.
timefmtgives the server a new format to use when providing dates. This is a string compatible with the
strftimelibrary call under most versions of UNIX.
sizefmtdetermines the formatting to be used when displaying the size of a file. Valid choices are
bytes, for a formatted byte count (formatted as 1,234,567), or
abbrevfor an abbreviated version displaying the number of kilobytes or megabytes the file occupies.
