+=head1 CAVEATS
+
+As dependency module code is copied into the resulting file as text, only
+pure-perl dependencies can be packed, not compiled XS code.
+
+The currently-installed dependencies to pack are found via F<.packlist> files,
+which are generally only included in non-core distributions that were installed
+by a CPAN installer. This is a feature; see L<fatpack/packlists-for> for
+details. (a notable exception to this is FreeBSD, which, since its packaging
+system is designed to work equivalently to a source install, does preserve
+the packlist files)
