Here is how I decided to proceed for now, in case anyone is amused by my
little problems.  I just created a file *org-stamps* having three
columns for each publishable Org file: a time stamp, a md5sum over all
publishable parts, and the Org file name.

The very first time, or for any new Org file, the time stamp is the file
modification time.  For each Org file, the tool generating the index
pages recomputes the md5sum over all publishable parts and compares with
the md5sum from *org-stamps*; if they match, the *org-stamps* time stamp
is used instead of the actual file time stamp.  If they do not match,
the current file time stamp and md5sum are going to obliterate the
values saved in *org-stamps* once all Org files will have been

Simple enough for now, I guess.
