(defvar gnus-summary-line-format "%U\%R\%z\%I\%(%[%4L: %-20,20n%]%) %s\n"
  "*The format specification of the lines in the summary buffer.

It works along the same lines as a normal formatting string,
with some simple extensions.

%N   Article number, left padded with spaces (string)
%S   Subject (string)
%s   Subject if it is at the root of a thread, and \"\" otherwise (string)
%n   Name of the poster (string)
%a   Extracted name of the poster (string)
%A   Extracted address of the poster (string)
%F   Contents of the From: header (string)
%x   Contents of the Xref: header (string)
%D   Date of the article (string)
%d   Date of the article (string) in DD-MMM format
%M   Message-id of the article (string)
%r   References of the article (string)
%c   Number of characters in the article (integer)
%L   Number of lines in the article (integer)
%I   Indentation based on thread level (a string of spaces)
%T   A string with two possible values: 80 spaces if the article
     is on thread level two or larger and 0 spaces on level one
%R   \"A\" if this article has been replied to, \" \" otherwise (character)
%U   Status of this article (character, \"R\", \"K\", \"-\" or \" \")
%[   Opening bracket (character, \"[\" or \"<\")
%]   Closing bracket (character, \"]\" or \">\")
%>   Spaces of length thread-level (string)
%<   Spaces of length (- 20 thread-level) (string)
%i   Article score (number)
%z   Article zcore (character)
%t   Number of articles under the current thread (number).
%e   Whether the thread is empty or not (character).
%l   GroupLens score (string).
%P   The line number (number).
%u   User defined specifier.  The next character in the format string should
     be a letter.  Gnus will call the function gnus-user-format-function-X,
     where X is the letter following %u.  The function will be passed the
     current header as argument.  The function should return a string, which
     will be inserted into the summary just like information from any other
     summary specifier.

Text between %( and %) will be highlighted with `gnus-mouse-face'
when the mouse point is placed inside the area.  There can only be one
such area.

The %U (status), %R (replied) and %z (zcore) specs have to be handled
with care.  For reasons of efficiency, Gnus will compute what column
these characters will end up in, and \"hard-code\" that.  This means that
it is illegal to have these specs after a variable-length spec.  Well,
you might not be arrested, but your summary buffer will look strange,
which is bad enough.

The smart choice is to have these specs as for to the left as
possible.

This restriction may disappear in later versions of Gnus.")
