 16 * 
 17 * this file creates necessary data files for nimisewi.c.
 18 * 
 19 * i thought that it would be stupid to hardcode all the tokipona words into
 20 * actual code, so this little program is created. it reads nimitoki.txt file
 21 * which is in such format that one word is on separate line. i hope it's
 22 * easy now to add and remove desired words.
 23 * 
 24 * it's use is very narrow and tied to nimisewi.c, but it could be adapted.
 25 * 
 26 * TODO: make use of templates, maybe?
