Usage:
      sfdmeld [-a ap.xml] [-p] structure.sfd design.sfd output.sfd

    Merges two FontForge font files such that the lookups and behaviour in
    the second (design) file is overridden by that in the first file. So for
    example, which attachment points a glyph has are governed by the
    structure file but their positions are taken from the design file.
    Lookups are taken from the structure file.

Options:
      -a file.xml   Optional AP database to merge APs from
      -h            print manpage
      -p            Take attachment point positions from the structure file
