57 | =head1 DESCRIPTION | ||||
58 | |||||
59 | Module::Find lets you find and use modules in categories. This can be very | ||||
60 | useful for auto-detecting driver or plugin modules. You can differentiate | ||||
61 | between looking in the category itself or in all subcategories. | ||||
62 | |||||
63 | If you want Module::Find to search in a certain directory on your | ||||
64 | harddisk (such as the plugins directory of your software installation), | ||||
65 | make sure you modify C<@INC> before you call the Module::Find functions. | ||||
66 | |||||
67 | =head1 FUNCTIONS | ||||
68 | |||||
69 | =over | ||||
70 | |||||
71 | =item C<setmoduledirs(@directories)> | ||||
72 | |||||
73 | Sets the directories to be searched for modules. If not set, Module::Find | ||||
74 | will use @INC. If you use this function, @INC will I<not> be included | ||||
75 | automatically, so add it if you want it. Set to undef to revert to | ||||
76 | default behaviour. | ||||
77 | |||||

82 | } | ||||
83 | |||||
84 | =item C<@found = findsubmod Module::Category> | ||||
85 | |||||
86 | Returns modules found in the Module/Category subdirectories of your perl | ||||
87 | installation. E.g. C<findsubmod CGI> will return C<CGI::Session>, but | ||||
88 | not C<CGI::Session::File> . | ||||

96 | } | ||||
97 | |||||
98 | =item C<@found = findallmod Module::Category> | ||||
99 | |||||
100 | Returns modules found in the Module/Category subdirectories of your perl | ||||
101 | installation. E.g. C<findallmod CGI> will return C<CGI::Session> and also | ||||
102 | C<CGI::Session::File> . | ||||

113 | |||||
114 | Uses and returns modules found in the Module/Category subdirectories of your perl | ||||
115 | installation. E.g. C<usesub CGI> will return C<CGI::Session>, but | ||||
116 | not C<CGI::Session::File> . | ||||

136 | |||||
137 | Uses and returns modules found in the Module/Category subdirectories of your perl installation. E.g. C<useall CGI> will return C<CGI::Session> and also | ||||
138 | C<CGI::Session::File> . | ||||
