Hi Is this really needed? I look at the webpages when importing stuff.
For npm Julien and I created a special tool to do the job of fetching the dependencies. You could easily roll-your-own and change (call-with-temporary-output... -> (call-with-output-file ...) As it is only Hartmut who asked for this during 2 years of everyone using the importer I vote for closing this as "won't fix". -- Cheers Swedebugia
