+# Each instance is parametrized with two functions, one that is
+# supposed to return the current time, one that is supposed to
+# implement a delay.  You can implement fine- or course-grained
+# real-time scheduling by substituting time and sleep or millitimer
+# and millisleep from the built-in module time, or you can implement
+# simulated time by writing your own functions.  This can also be
+# used to integrate scheduling with STDWIN events; the delay function
+# is allowed to modify the queue.  Time can be expressed
+# as integers or floating point numbers, as long as it is consistent.
+
+# Events are specified by tuples (time, priority, action, argument).
+# As in UNIX, lower priority numbers mean higher priority; in this
+# way the queue can be maintained fully sorted.  Execution of the
+# event means calling the action function, passing it the argument.
+# Remember that in Python, multiple function arguments can be packed

+# A FormSplit lets you place its children exactly where you want them
+# (including silly places!).
+# It does no explicit geometry management except moving its children
+# when it is moved.
+# The interface to place children is as follows.
+# Before you add a child, you may specify its (left, top) position
+# relative to the FormSplit.  If you don't specify a position for
+# a child, it goes right below the previous child; the first child
+# goes to (0, 0) by default.
+# NB: This places data attributes named form_* on its children.
+# XXX Yes, I know, there should be options to do all sorts of relative
+# placement, but for now this will do.
