-A command-line {\em switch} is (generally) either on or off; e.g., the
-``verbose'' (-v) switch is either on or off. (The \tr{-G<group>}
-switch is an exception; it's set to a string, or nothing.)

+\subsection{Command-line options}
+%* *
+%************************************************************************
+
+The hsc command-line options are split into two categories:
+
+ - static flags
+ - dynamic flags
+
+Static flags are represented by top-level values of type Bool or Int,
+for example. They therefore have the same value throughout the
+invocation of hsc.
+
+Dynamic flags are represented by an abstract type, DynFlags, which is
+passed into hsc by the compilation manager for every compilation.
+Dynamic flags are those that change on a per-compilation basis,
+perhaps because they may be present in the OPTIONS pragma at the top
+of a module.
+
+Other flag-related blurb:
A list of {\em ToDo}s is things to be done in a particular part of
processing. A (fictitious) example for the Core-to-Core simplifier
(\tr{simplCore/SimplCore.lhs), and in the STG-to-STG processing loop
(\tr{simplStg/SimplStg.lhs}).
