    For your interest, I just published an article about the minimal version of Make (written in a page of AWK) that's included in the book "The AWK Programming Language":

    https://benhoyt.com/writings/awk-make/

    It's a neat program, and in the article I describe how it works, as well as porting it to a Python version for comparison.

    The Make program is included in the second edition of the book, which is coming out next month!

    Nice. Just FYI, the gawk filefuncs extension does include a stat() function that would enable you to
    eliminate the ages function and age map just as in Python. See "man 3am filefuncs" or the manual:

    And of course gawk also has true multi-dimensional arrays, so that could also make things prettier
    and more concise.

    Regards,
    Andy

    Ah, excellent, thanks for the link. Yeah, that's much more direct (and more efficient!) than shelling out to "stat" as I did in my modified AWK version. (Though for the book I'm pretty sure Kernighan et al are trying to stick to standard AWK features.)
