+Thun in C
+---------------
+
+This is my first attempt to write C in many years, I hope it's not too
+embarassing.
+
+I use Gperf to create a static wordlist.  This make word lookup very
+efficient, but there's no way currently to add definitions at runtime.
+
+There's a janky script *convert\_defs.py* that generates *definitions.c*,
+*definitions.h*, and *KEYWORDS.txt* from the *defs.txt* file.  I would
+like to replace the dependency on Python with, say, Awk or something.
