Extensive additional documentation for Perl modules is available. Thedefault configuration for perl will place this additional documentationin the F</usr/local/lib/perl5/man> directory (or else in the F<man>subdirectory of the Perl library directory). Some of this additionaldocumentation is distributed standard with Perl, but you'll also finddocumentation for third-party modules there.⌨️ 快捷键说明
