I was just merging your changes, and realized that gmail may have dropped
your schedtool-dl recipe.

Can you resend it with your updated series ? I have another schedtool
recipe here, but it's against an older sched_dl release, so I'd like to
compare it to yours and merge the two of them together.

Cheers,

Bruce
