note bart There are some tricks one could use the see what modules are installed most recently. <p>You can check the "ctime" of those module files. Unless you did something funky to your filesystem, this should be quite a reliable source for candidate modules to uninstall. <p>And <c>perldoc perllocal</c> lists the contents of <c>perllocal.pod</c>, which ought to be updated with new module additions, including date of installation, with every installation using [doc://CPAN], and hopefully, with replacements of [doc://CPAN], too. (I think I recall that that PPM, (originally) ActiveState's alternative module installer for Windows, doesn't update it.) 998787 998801
