+
+Assuming this action is added to the @code{example} service, then you can do:
+
+@example
+# herd say-hello example
+Hello, friend! arguments: ()
+# herd say-hello example a b c
+Hello, friend! arguments: ("a" "b" "c")
+@end example
+
+This, as you can see, is a fairly sophisticated way to say hello.

+the dungeon and not simply killing everything in sight - in fact, killing
+everything in sight is a good way to die quickly.  Each game presents a
+different landscape - the random number generator provides an essentially
+unlimited number of variations of the dungeon and its denizens to be discovered
+by the player in one of a number of characters: you can pick your race, your
+role, and your gender.")

+Subject: [PATCH] pdfwrite - Guard against trying to output an infinite number
+
+Bug #699255 " Buffer overflow on pprintg1 due to mishandle postscript file data to pdf"
+
+The file uses an enormous parameter to xyxhow, causing an overflow in
+the calculation of text positioning (value > 1e39).
+
+Since this is basically a nonsense value, and PostScript only supports
+real values up to 1e38, this patch follows the same approach as for
+a degenerate CTM, and treats it as 0.
+
+Adobe Acrobat Distiller throws a limitcheck error, so we could do that
+instead if this approach proves to be a problem.

+Subject: [PATCH] Include <QRegExpValidator> explicitly
+
+Since Qt 5.11, generated ui_getprofilename.h no longer includes QHeaderView
+which breaks the chain that included qvalidator.h in getprofilename.cpp.
+As it feels rather fragile to rely on such indirect includes, let's include
+<QRegExpValidator> explicitly in each file using QRegExpValidator class.

+
+    modesetting: use drmmode_bo_import() for rotate_fb
+    
+    drmmode_shadow_allocate() still uses drmModeAddFB() which may fail if
+    the format is not as expected, preventing from using a rotated output.
+    
+    Change it to use the new function drmmode_bo_import() which takes care
+    of calling the drmModeAddFB2() API.
