High-Level Design
Having dealt with these general issues we can now lay out the high-level design of our utilities. All the utilities for which the legacy format is the source format share a common structure, as do all for which the legacy format is the target format. Both sets are built on several common classes developed in this chapter. Derived classes specific to the legacy format are built in each of the next three chapters.
