- with some simple extensions.

- %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).
- %V Total thread score (number).
- %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.
