How can I configure perlcritic?

How do I configure ActiveState perlcritic? The Perl installation doesn’t seem to have set the PERLCRITIC environment variable. I can see that UserProfile.pm looks for “.perlcriticrc” in the user’s home directory, but I don’t know what that directory is. There is no file by that name in my C:\Users folder and I can’t find such a file. (I’m using Perl 5.20 because later ActiveState versions don’t permit me to simply open a command window anywhere and run a Perl script.) Thanks.

Are you using 5.38+? Perlcritic is not working - #4 by marcg
