Classes with mc Configuration

In configuring with the mc technique, many classes are defined for your convenience. You need to be aware of these, not only to take advantage of them, but also to avoid reusing their names by mistake. Table 22-2 lists all the macros that the mc technique uses as of version 8.12. Most are described in other sections, but a few are described here. See a description of LOCAL_CONFIG (Section 4.3.3.1) for the general method used for adding members and new class names using the mc configuration technique.
