I renamed the new makeinfo to makeinfo5, and keep the old v4.x one under the name makeinfo. > I still have no idea how they managed to slow things down so much. Because they implemented makeinfo in Perl, and made it a real translator, that builds an intermediate parse tree representation, and then invokes an appropriate back-end to produce output. By contrast, the original makeinfo was a one-pass converter which left most of the text intact and just acted on the few directives, expanding them in-line. > It feels like it's a good 100 times slower.
