+    This pen can be used to check if a glyph's contents (outlines plus
+    components) have changed.
+
+    Components are added as the original outline plus each composite's
+    transformation.
+
+    Example: You have some TrueType hinting code for a glyph which you want to
+    compile. The hinting code specifies a hash value computed with HashPointPen
+    that was valid for the glyph's outlines at the time the hinting code was
+    written. Now you can calculate the hash for the glyph's current outlines to
+    check if the outlines have changed, which would probably make the hinting
+    code invalid.
+
+    > glyph = ufo[name]
+    > hash_pen = HashPointPen(glyph.width, ufo)
+    > glyph.drawPoints(hash_pen)
+    > ttdata = glyph.lib.get("public.truetype.instructions", None)
+    > stored_hash = ttdata.get("id", None)  # The hash is stored in the "id" key
+    > if stored_hash is None or stored_hash != hash_pen.hash:
+    >    logger.error(f"Glyph hash mismatch, glyph '{name}' will have no instructions in font.")
+    > else:
+    >    # The hash values are identical, the outline has not changed.
+    >    # Compile the hinting code ...
+    >    pass
+
+    If you want to compare a glyph from a source format which supports floating point
+    coordinates and transformations against a glyph from a format which has restrictions
+    on the precision of floats, e.g. UFO vs. TTF, you must use an appropriate rounding
+    function to make the values comparable. For TTF fonts with composites, this
+    construct can be used to make the transform values conform to F2Dot14:
+
+    > ttf_hash_pen = HashPointPen(ttf_glyph_width, ttFont.getGlyphSet())
