----------------------------------------------------------------+-----------
 In the description of the Perl syntax for regex (
 http://www.boost.org/doc/libs/1_53_0/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html

 ), in the Negation paragraph, it is written:
 "
 If the bracket-expression begins with the ^ character, then it matches the
 complement of the characters it contains, for example =a-c= matches any
 character that is not in the range a-c.
 "

 However, the regex =a-c= actually matches the string =a-c=, contrary to
 what the example says. It should be [!^a-c] instead of =a-c=.

 Also, in both paragraphs above ("character ranges" and "single
 characters") regexes like =[abc]= and =[a-c]= are used in place of [abc]
 and [a-c], respectively.
