NAME vendorlib - Use Only Core and Vendor Libraries in @INC SYNOPSIS #!/usr/bin/perl use vendorlib; use strict; use warnings; use SomeModule; # will only search in core and vendor paths ... DESCRIPTION In a system distribution such as Debian, it may be advisable for Perl programs to ignore the user's CPAN-installed modules and only use the distribution-provided modules to avoid possible breakage with newer and unpackaged versions of modules. To that end, this pragma will replace your @INC with only the core and vendor @INC paths, ignoring site_perl and $ENV{PERL5LIB} entirely. It is recommended that you put use vendorlib; as the first statement in your program, before even use strict; and use warnings;. ACKNOWLEDGEMENTS Thanks to mxey, jawnsy and ribasushi for help with the design. AUTHOR Rafael Kitover
