That's right -- and the devil would be in the incomplete/incorrect details. Areas of special pain: (1) cross-directory constraints, (2) derivations, (3) multiple port tree apexes. These are all areas where CML1 has design flaws that human coders get around by applying higher-level knowledge of a kind a mechanical translator couldn't have.
This is, alas, one of those cases where the first 90% of the problem looks easy and the last 10% turns ought to be nigh-impossible -- and the first 90% is useless without the last 10%. -- <a href="http://www.tuxedo.org/~esr/">Eric S. Raymond</a>
