          Spell looks up words from the named files (standard input
          default) in a spelling list and places possible
          misspellings-words not sanctioned there-on the standard out-

          Spell ignores constructs of troff(1) and its standard pre-
          processors.  It understands these options:

          -b   Check British spelling.

          -v   Print all words not literally in the spelling list,
               with derivations.

          -x   Print on standard error, marked with `=', every stem as
               it is looked up in the spelling list, along with its
               affix classes.

          As a matter of policy, spell does not admit multiple spel-
          lings of the same word.  Variants that follow general rules
          are preferred over those that don't, even when the unruly
          spelling is more common.  Thus, in American usage, `mod-
          elled', `sizeable', and `judgment' are rejected in favor of
          `modeled', `sizable', and `judgement'.  Agglutinated vari-
          ants are shunned: `crewmember' and `backyard' cede to `crew
          member' and  `back yard' (noun) or `back-yard' (adjective).

          /bin/aux/sprog    The actual spelling checker.  It expects
                            one word per line on standard input, and
                            takes the same arguments as spell.

          The heuristics of deroff(1) used to excise formatting infor-
          mation are imperfect.

          The spelling list's coverage is uneven; in particular biol-
          ogy, medicine, and chemistry, and perforce proper names, not
          to mention languages other than English, are covered very
