Subject: moved some code around and finished basic page generation it is far
 too hacky though, createtmpfile() is an ugly hack that cannot stay. the
 problem is replaceinpage() and the functions it calls expects a file name
 that it opens, i cannot just pass it a string. i need to figure out a better
 solution
