It performs basic syntactic transformations such as adding package declarations, converting require statements, and updating subroutine definitions to follow Perl 5 module conventions.Part of the standard Perl distribution, the conversion is approximate and the output typically requires manual review and adjustment to produce fully functional Perl 5 modules.
