Re: Handling expensive packages

[jbranso]

Hey Peter!

Your patch found its way on onto the guix devel list!

Thanks for contributing to guix!  We want to add your patch, and we are 
wondering what your motivation was for sending this patch?  Is your patch a 
prerequisite for a package you want to add?  Or do you have some other reason?

Thanks,

Joshua
