EXPORT

        [GTVL\]EXPORT FileName [DirName]

    Export the current (or specified) directory tree to an external metacode
    file  of  name FileName. The default extension is .meta, and these files
    have a different format than the old .vec files. The sub-plot can  later
    be  reincorporated  using  command  IMPORT.  This allows merging several
    plots together. This command does an implicit COMPRESS before saving the
    tree, so that invisible subtrees will be deleted.
