+ with some simple extensions.
+
+ %N Article number, left padded with spaces (string)

+ %s Subject if it is at the root of a thread, and \"\" otherwise (string)

+ %A Extracted address of the poster (string)
+ %F Contents of the From: header (string)
+ %f Contents of the From: or To: headers (string)

+ %D Date of the article (string)
+ %d Date of the article (string) in DD-MMM format
+ %o Date of the article (string) in YYYYMMDD`T'HHMMSS format
+ %M Message-id of the article (string)
+ %r References of the article (string)
+ %c Number of characters in the article (integer)
+ %k Pretty-printed version of the above (string)
+ For example, \"1.2k\" or \"0.4M\".
+ %L Number of lines in the article (integer)
+ %I Indentation based on thread level (a string of spaces)
+ %B A complex trn-style thread tree (string)
+ The variables `gnus-sum-thread-*' can be used for customization.
+ %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).
+ %O Download mark (character).
+ %* If present, indicates desired cursor position
+ (instead of after first colon).
+ %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.
+
+ 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 invalid 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 far to the left as
+ possible.
+
+ This restriction may disappear in later versions of Gnus.
+
+ General format specifiers can also be used.
