Simple HTML preprocessor for "compile time"

my question is, is there a preprocessor for HTML like php which runs not when a user does a call. It needs to run at some kind of build stage to do some includes an so on to make some modular HTML pages (nav in one file, footer in an other file and some real page files which are including the footer and nav file) so that I only need to change the nav content and the nav is changed on all "real" pages
