The dependency will be substituted into your package's F +file wherever you place the token B<${perl:Depends}>. -It will also look at #! lines of perl scripts in order to be able -to calculate a dependency for perl scripts and not only perl modules. - -In addition it will automatically remove .packlist file and will -remove the directory in which it was if it's empty.
