This is the Perl distribution Package-DeprecationManager. Installing Package-DeprecationManager is straightforward. ## Installation with cpanm If you have cpanm, you only need one line: % cpanm Package::DeprecationManager If it does not have permission to install modules to the current perl, cpanm will automatically set up and install to a local::lib in your home directory. See the local::lib documentation (https://metacpan.org/pod/local::lib) for details on enabling it in your environment. ## Installing with the CPAN shell Alternatively, if your CPAN shell is set up, you should just be able to do: % cpan Package::DeprecationManager ## Manual installation As a last resort, you can manually install it. Download the tarball, untar it, then build it: % perl Makefile.PL % make && make test Then install it: % make install If your perl is system-managed, you can create a local::lib in your home directory to install modules to. For details, see the local::lib documentation: https://metacpan.org/pod/local::lib ## Documentation Package-DeprecationManager documentation is available as POD. You can run perldoc from a shell to read the documentation: % perldoc Package::DeprecationManager
