Both Python & Perl have CSV parsing modules, and can of course deal
with fixed-width data, let you skip comments, commit every N rows,
skip over committed records in can the load crashes, etc, etc, etc.
Probably not what you wanted to read, though, since performance
takes a big hit. But it definitely works...

For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
