# vendorlib(3pm)

Use Only Core and Vendor Libraries in @INC

## 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.
