Some scripts, like delete_items.pl for example, have a -where parameter which allows for SQL statements to be used as additional parameters. It would be useful to have a similar -where parameter in the batch delete patrons script. Library teams have different requirements regarding which patrons should be deleted (and when), and even their own definition of inactive patrons. Having a -where parameter would offer them more flexibility to automatically delete patrons using the script, rather than having to do this manually.
