 two letters (ie. no punctuation).  The tool also ignores digits, since they
 typically have a fixed width and no kerning by design.
 
-To inspect the pairs reported, you can use the `kern_pair.py` tool:
+A file `kerned.pdf` is always generated, with each page showcasing one pair

 In the `kern.png` image, the first line is with no kerning. The second line
 is the tool's suggestion, and the third line is the existing font
-kerning.  The `kerned.png`, the pair is showcased between lower, and upper,

 letters.  The three rows, similarly, show no-kerning, tool's suggestion,
 and existing kern.
