The stampinclude package v1.0 has been released. It replaces \includeonly and will select the files for inclusion by inspecting the time stamp of the .aux files. Files will be selected for inclusion if the .aux file doesn’t yet exist or if it’s older than the corresponding .tex file. stampinclude does a similar job like the askinclude package but not interactively. The pdftex command \pdffilemoddate is internally used, \include is redefined and \includeonly is ignored.
