Trace Utilities

Hi. Does anyone know how does one write a trace utility (for code debugging purposes), or can point me to some articles/tutorials/papers? I''ve tried to search google, but didn''t find anything useful... Alternatively, does anyone know of a free trace tool/library compatible with Delphi and Kylix?
