 2 *
 3 * this file creates necessary data files for nimisewi.c.
 4 *
 5 * i thought that it would be stupid to hardcode all the tokipona words into
 6 * actual code, so this little program is created. it reads nimitoki.txt file
 7 * which is in such format that one word is on separate line. i hope it's
 8 * easy now to add and remove desired words.
 9 *
10 * it's use is very narrow and tied to nimisewi.c, but it could be adapted.
11 * 
12 * TODO: make use of templates, maybe?
