Mick O'Donnell's
RSTTool
is a program for constructing RST analyses. What SmART is in relation to SSA, RSTTool
is in relation to RST. Alternative tools for RST analysis are Daniel Marcu's
RST Annotation Tool
and Hatem Ghorbel's
RhetAnnotate.
Unicode resources, especially for classicists, are available at David Perry's
scholarsfonts.net. The
Cardo font is part of the SmART package (see
Third-Party Tools).
A respectable collection of links to other unicode polytonic greek resources
is provided by
Russell Cottrell.
