+ * upb - a minimalist implementation of protocol buffers.
+ *
+ * A context represents a namespace of proto definitions, sort of like
+ * an interpreter's symbol table.  It is empty when first constructed.
+ * Clients add definitions to the context by supplying serialized
+ * descriptors (as defined in descriptor.proto).
