+Themes
+
+To generate samples of themes, first execute the 'run' script to generate the
+sample data.  Note that this data may need to be tweaked to include qualities
+that need to be illustrated in theme sample.
+
+Then edit the 'rc' file to include the desired theme file.
+
+Then run 'per' once per theme, and capture the display.
+
+Note that this will require that the terminal window be switched between a black
+and white background to properly show the light and dark themes.
+
+Note that for the solarized themes, the terminal color palette needs to be set
+to specific colors.
