+//
+// C++ assumptions:
+//
+// To ensure portability to many platforms, both new and old, we make
+// few assumptions about the C++ compiler and library.  For example,
+// we do not expect STL, templates or namespaces to be available.  The
+// "newest" C++ feature used is exceptions, which are used liberally
+// to transmit error information.  Even the use of exceptions can be
+// disabled at runtime, see setErrorModel().
+//
+// C++ naming conventions:
+//
+//  - All top level class names start with Db.
+//  - All class members start with lower case letter.
+//  - All private data members are suffixed with underscore.
+//  - Use underscores to divide names into multiple words.
+//  - Simple data accessors are named with get_ or set_ prefix.
+//  - All method names are taken from names of functions in the C
+//    layer of db (usually by dropping a prefix like "db_").
+//    These methods have the same argument types and order,
+//    other than dropping the explicit arg that acts as "this".
+//
+// As a rule, each DbFoo object has exactly one underlying DB_FOO struct
+// (defined in db.h) associated with it.  In many cases, we inherit directly
+// from the DB_FOO structure to make this relationship explicit.  Often,
+// the underlying C layer allocates and deallocates these structures, so
+// there is no easy way to add any data to the DbFoo class.  When you see
+// a comment about whether data is permitted to be added, this is what
+// is going on.  Of course, if we need to add data to such C++ classes
+// in the future, we will arrange to have an indirect pointer to the
+// DB_FOO struct (as some of the classes already have).
