a) In mixed case text, periods followed by whitespace followed
by a lower case letters are not sentence boundaries.

b) Periods followed by a digit with no intervening whitespace
are not sentence boundaries.

c) Periods followed by whitespace and then an upper case
letter, but preceded by any of a short list of titles are not sentence
boundaries. Sample titles include Mr., Mrs., Sr., HMS., Amb. and so
on.

d) Periods internal to a sequence of letters with no adjacent
whitespace are not sentence boundaries (for example, www.aptex.com, or
e.g).

e) Periods before double line-ends are probably sentence
boundaries.

f) Periods followed by certain kinds of punctuation (notably comma
and more periods) are probably not sentence boundaries.
