+/// \brief Implements a class for specifying sets of names and number ranges to
+/// match against.  This is specified as a comma-separated list of clauses.
+/// Each clause optionally starts with '-' to indicate exclusion instead of
+/// inclusion.  A clause can be a name, or a numeric range X:Y, or a single
+/// number X.  The X:Y form indicates a range of numbers greater than or equal
+/// to X and strictly less than Y.  A missing "X" is taken to be 0, and a
+/// missing "Y" is taken to be infinite.  E.g., "0:" and ":" specify the entire
+/// set.
+///
+/// This is essentially the same implementation as in szbuild.py, except that
+/// regular expressions are not used for the names.
