+List games on tours of tournament
+
+Usage: $argv0 [options] [tours]
+  Tournament tours are restricted to sequence \`tours' given in
+  Bash-style syntax, i.e., \`tours' may include explicit numbers
+  (tours=1 3), intervals (tours={1..5}), or any combination of them.
+  If no tours are specified, display each tour until an empty
+  \`tour_info' is found. By default, only unaccomplished games are
+  listed.
+
+  Inner variable REPO points to the root of repository; REPO is a URL
+  link, absolute or relative path. Inner variable TOURNAMENT specifies
+  the sub-directory of tournament.
+
+Options:
+  -a            List accomplished games too
+  -p PLAYER     Only PLAYER's games are listed; this supports globs
+                inside PLAYER for player matching
+  -f FORMAT     Specify the output format; FORMAT is \`term'
+                (default), \`html', or \`lor'
+  -l            Add the URL link to game (if accomplished)
+  -h            Show this help output
+  -v            Show version information
