+@section Viewing a Unifont File Interactively
+
+The @code{unifont-viewer} Perl script uses the @code{wxWidgets} Perl library
+to present a dynamic graphical representation of a Unifont hex file.
+This is a convenient way to scan quickly through a complete Unifont hex file.
+It is ideal for scanning through a Unifont hex source file after you have made
+changes.
+
+Use @code{unifont-viewer} to open any Unifont hex file, whether in the Basic
+Multilingual Plane up to the maximum Unicode code point of U+10FFFF. The font
+is displayed graphically in sections of 16-by-16 glyph grids (256 glyphs---a
+"page" in Unifont lingo). The page numbers (the upper portion of the
+hexadecimal code point range) appear in a list along the left-hand side.
+Only page ranges that are present in the Unifont hex file are listed.
+
+When @code{unifont-viewer} loads a hex file, it begins by displaying the first
+"page" range in that file.
