// KWIC = keyword-in-context.

// Read a file of words and create an ordered list of keywords, giving

// for each keyword a list of the contexts in which it appears.  For

// instance, for this text

This book presents C# version 2.0 as used in Microsoft Visual Studio

2005, including generics, iterators, anonymous methods and partial

type declarations, but excluding most of Microsoft's .Net Framework

class libraries except threads, input-output, and generic collection

classes.  The book does not cover unsafe code, destructors,

finalization, reflection, pre-processing directives (#define,

#if) or details of \textsc{ieee754} floating-point

numbers.

// the resulting list may look like this:

// How to proceed: (1) read a stream of words from file; (2) turn this

// into a stream of (2n+1)-tuples of words, namely a keyword

// surrounded by n words on either side; (3) create a dictionary

// mapping each keyword to a set of its contexts; (4) output the

// entries of the dictionary sorted by keyword, for each keyword

// building an HTML <item> list or similar.

// Step (2) can be improved by not generating (2n+1)-tuples for

// keywords that are stop words (in, of, the, a, ...).  Also, each

// such triple may have an associated line number or page number on

// which it appears, in which case the dictionary should map to a

// dictionary that maps each context to a list of line numbers or page

// numbers.
