This pragma tells the compiler to enable (or disable) the use of POSIX locales for built-in operations (LC_CTYPE for regular expressions, and
LC_COLLATE for string comparison). Each ``use locale'' or ``no locale''
affects statements to the end of the enclosing BLOCK.
perldoc2tree.cgi: /usr/lib/perl5/5.8.8/locale.pm: cannot resolve L in paragraph 9.
See perllocale for more detailed information on how Perl supports
locales.
