London Underground Map Data - Program Explanation

The program I've written to interpret the station data file is designed to do two things:

convert the station data into a set of equivalent SQL insert statements (see Why SQL?)
provide some reporting facilities which allow the data to be verified

At this time, I'm not going to explain very much of this. The data structures and equivalent database tables are rexplained elsewhere, and the verification reports aren't really very good. Fundamentally, I would say "Use the source!"

What I will say is that the program works by reading the data file into a set of data structures internally representing data, and then traverses the data in different ways to produce the SQL output and so on.

The program is written in C++ using MFC data structures (because they're the ones I know best, not because they're any good particularly) and is compiled to run on Win32 platforms (well, I've run it on two).
