+# there are two implementations available here
+# one shows up in the main page like a regular part of the page,
+# while the other one relies on transient popups
+# by default we use the latter, but you can specify
+# transient=False if you want to use the former
+# xxx
+# also the pieces that go with this transient mode are
+# under views/templates, it would make sense to move them over here
+# however it turns out that views/templates/base.html unconditionnally
+# includes messages-transient-header.html
