There is also some time() and localtime() calls (in z27.c and
z35.c). Perhaps Lout should also call stat() to get the modification
time of files. This would enable the recreation of *.li files from
*.ld files automagically. (of course timestamping test could be leaved
to a utility like make).

IMHO the only difficulty (outside the system(3) library call) is the filenames.

On MessyLoss, there is that damned 8+3 name limit. Perhaps the .lout
extension should become (on MsDog only - please don't change it on
Unix) .lot or .lou.

Also, on some occasions Lout add an extension to a existing file. For
instance, i have some @Cite{$..} in my bibliographical database file
eumref.ld (because for an article InBook the InTitle contains a
@Cite{$..}). This makes lout create an eumref.ld.ld file.
