- *
- * Purpose:
- * A merge of Bjorn Reese's format() function and Daniel's dsprintf()
- * 1.0. A full blooded printf() clone with full support for <num>$
- * everywhere (parameters, widths and precisions) including variabled
- * sized parameters (like doubles, long longs, long doubles and even
- * void * in 64-bit architectures).
- *
- * Current restrictions:
- * - Max 128 parameters
- * - No 'long double' support.
- *
- * If you ever want truly portable and good *printf() clones, the project that
- * took on from here is named 'Trio' and you find more details on the trio web
- * page at http://daniel.haxx.se/trio/
