Taxacom: Big changes / increases in virus taxonomy - who knew?

[Tony Rees]

Hi Bevan, I purposefully refrained from including the changeover from the
previous "vernacular style" species names to new, binomial style names of
the "genus species" type as adopted in other groups for many centuries now,
but yes, that is an additional, and non trivial, issue to be managed by all
compilers of such names.

Regards, Tony
