+ If a TRANSLATION table is present it is assumed that only the tip
+ labels are translated and they are all translated with integers
+ without gap. Consequently, if nodes have labels in the tree(s) they
+ are read as they are and not looked for in the translation table. The
+ logic behind this is that in the vast majority of cases, node labels
+ will be support values rather than proper taxa names. This is
+ consistent with \code{\link{write.nexus}} which translates only the
+ tip labels.
