Spell is the \s-1MINIX 3\s-1 spelling checker. It is actually a short shell script. First, the program prep strips off the roff, nroff, and troff control lines, and the punctuation, and lists each word on a separate line. These words are then sorted. The resulting output is then compared to the dictionary. Words present in the file but not present in the dictionary are listed. The dictionary must be located in /usr/lib/dict/words.

nroff (1), prep (1).
