How do I find and remove unused Perl modules

To find and remove unused Perl modules in your project, you can use tools and methods that analyze your codebase and report modules that are not being used. Below is an example approach using the `devel-nytprof` module, which can help you identify unused modules.


        # Install Devel::NYTProf
        cpan Devel::NYTProf
        
        # Run your script with Devel::NYTProf
        perl -d:NYTProf your_script.pl
        
        # Generate a report
        nytprofhtml --file nytprof.out
        
        # Check the report for unused modules
        open('nytprof/index.html')

After identifying unused modules, you can remove them from your project by editing your makefile or the files where they are declared.
