15: .SH DESCRIPTION
16: .I Spell
17: looks up words from the named
18: .I files
19: (standard input default)
20: in a public spelling list and in a private list.
21: Possible misspellings (words
22: that occur in neither and are not plausibly derivable
23: from the former) are placed on the standard output.
24: .PP
25: .I Spell
26: ignores constructs of
27: .IR troff (1)
28: and its standard preprocessors,
29: or constructs of
30: .IR tex (1).
31: It understands these options:
32: .TP
33: .B -b
34: Check British spelling.
35: .TP
36: .B -v
37: Print all words not literally in the spelling list, with
38: derivations.
39: .TP
40: .B -x
41: Print on standard error, marked with
42: .LR = ,
43: every stem as it is looked up in the spelling list,
44: along with its affix classes.
45: Typically used for maintenance.
46: .TP
47: .B -c
48: .br
49: .ns
50: .TP
51: .B -C
52: Input is one word per line.
53: Output is a single byte per word, delivered immediately:
54: .L -
55: if the word is rejected,
56: .L +
57: if the word is accepted under
58: .BR -c ,
59: and a digit if the word is accepted under
60: .BR -C .
61: Digit zero indicates a word known directly; larger
62: numbers indicate words derived by increasingly
63: elaborate paths.
64: Typically used by other programs piping queries to spell.
65: .PP
66: The private list, by default
67: .FR $HOME/lib/spelldict ,
68: is arranged one word per line.
69: .PP
70: Pertinent files may be specified by
71: environment variables, listed below with their default settings.
72: To help in gathering local vocabularies, copies of all output
73: are accumulated in the history file, if it exists and is writable.
74: .PP
75: As a matter of policy,
76: .I spell
77: does not admit multiple spellings of the same word.
78: Variants that follow general rules are preferred over
79: over those that don't, even when the unruly spelling is
80: more common.
81: Thus, in American usage, `modeled', `sizable', and `judgement' are
82: preferred to `modelled', `sizeable', and `judgment'.
83: Agglutinated variants are shunned: `crew member' and `back yard'
84: (noun) or `back-yard' (adjective) are preferred to
85: `crewmember' and `backyard'.
