+            #     filesize), which results in the pdf file being reported
+            #     as an INPUT file of pdflatex.
+            #     Without special precautions, latexmk gets into an
+            #     infinite loop.  But correct functioning is achieved
+            #     simply by ensuring that the pdf file is not inserted in
+            #     the list of source files for *latex.

+            # (b) The memoize package uses non-trivial content from the pdf
+            #     file.  There is a clear and essential circular
+            #     dependency.  But given the way the package and its
+            #     associated script work, the pdf file doesn't appear any
+            #     where relevant to be detected by latexmk, and the package
+            #     and its script take care such that all necessary reruns
+            #     by latexmk get done.
+            #     In addition, there is a special configuration --- see
+            #     example_rcfiles/memoize_latexmkrc --- to allow memoize to
+            #     be used properly with latexmk.  So that doesn't entail
+            #     special diagnosis here.
+            #
+            # The above illustrate that circular dependencies involving
+            # these normally output-only files can exist, legitimately.  So
+            # we have to allow for the situation.

+            # that the main pdf output file is listed in the .fls file, and
+            # so that we do need an explicit test.

+            # that can be generalized if need be.
+            #
+            # Given the vagaries of how the aux and output directories

+            # However, there are known situations where at least the pdf
+            # file does.  This siutation is potentially problematic, since
+            # some of these normally output-only files, including the pdf

+            # dependency involving such files, latexmk's normal methods
+            # give a perpetually out-of-date situation, and hence an
+            # infinite loop.

-            # Older versions of hyperxmp (e.g., 2020/10/05 v. 5.6) reported the pdf file
-            # as an input file.

+            # The known cases of the relevant kinds of circular dependency
+            # both involve the output pdf file:
+            #
+            # (a) hyperxmp in some versions, e.g., 2020/10/05 v. 5.6, reads
+            #     metadata of the pdf file produced by pdflatex (to get the
+            #     filesize), which results in the pdf file being reported
+            #     as an INPUT file of pdflatex.
+            #     Without special precautions, latexmk gets into an
+            #     infinite loop.  But correct functioning is achieved
+            #     simply by ensuring that the pdf file is not inserted in
+            #     the list of source files for *latex.
+            #     More recent versions of hyperxmp work differently, and so
+            #     do not cause 
+            #     
+            # (b) The memoize package uses non-trivial content from the pdf
+            #     file.  There is a clear and essential circular
+            #     dependency.  But given the way the package and its
+            #     associated script work, the pdf file doesn't appear any
+            #     where relevant to be detected by latexmk, and the package
+            #     and its script take care such that all necessary reruns
+            #     by latexmk get done.
+            #     In addition, there is a special configuration --- see
+            #     example_rcfiles/memoize_latexmkrc --- to allow memoize to
+            #     be used properly with latexmk.  So that doesn't entail
+            #     special diagnosis here.
+            #
+            # The above illustrate that circular dependencies involving
+            # these normally output-only files can exist, legitimately.  So
+            # we have to allow for the situation.
+            #
+            # The hyperxmp example shows that it does happen in reality
+            # that the main pdf output file is listed in the .fls file, and
+            # so that we do need an explicit test.
+            # But there are no other known situations for other classes of
+            # files that are normally only output (e.g., log, dvi, etc), so
+            # I'll restrict the detection to the pdf case, but in a form
+            # that can be generalized if need be.
+            #
+            # Given the vagaries of how the aux and output directories
+            # could be used, the test allows for the file being in any of
+            # the relevant directories.  There is a potential issue that
+            # different strings could be used for the name of the same
+            # directories. That would entail a fancier test, but that issue
+            # has not arisen in practice so far.  Since the cases where the
