202 The 'keyword' pointer provides the central word, which is surrounded-
203 by a left context and a right context. The 'keyword' and 'length'-
204 field allow full 8-bit characters keys, even including NULs. At other-
205 places in this program, the name 'keyafter' refers to the keyword-
206 followed by its right context.-
207-
208 The left context does not extend, towards the beginning of the file,-
209 further than a distance given by the 'left' value. This value is-
210 relative to the keyword beginning, it is usually negative. This-
211 insures that, except for white space, we will never have to backward-
212 scan the source text, when it is time to generate the final output-
213 lines.-
214-
215 The right context, indirectly attainable through the keyword end, does-
216 not extend, towards the end of the file, further than a distance given-
217 by the 'right' value. This value is relative to the keyword-
218 beginning, it is usually positive.-
219-
220 When automatic references are used, the 'reference' value is the-
221 overall line number in all input files read so far, in this case, it-
222 is of type intmax_t. When input references are used, the 'reference'-
223 value indicates the distance between the keyword beginning and the-
224 start of the reference field, and it fits in ptrdiff_t and is usually-
225 negative. */-
