36# The deferred commands are run in the order '.END .BEGIN all'.
37# This may be unexpected at first since the natural order would be
38# '.BEGIN all .END', but it is implemented correctly.

40# At the point where the commands of a node with deferred commands are run,
41# the deferred commands are appended to the commands of the .END node.
42# This happens in Compat_RunCommand, and to prevent an endless loop, the
43# deferred commands of the .END node itself are not appended to itself.
44# Instead, the deferred commands of the .END node are run as if they were
45# immediate commands.
