Thanks for adding TAGS

but I now get

ImportError: No module named datetime:
  File "SConstruct", line 18:
    import datetime

and so no build.

I have been looking into fout.c and there are a number of major design
problems.  I have code that should work for fout and foutk.  fiopen
does not seem to fit at all, and I have not really checked the others.
Will try to write it down today.
