Re: [coldsync-hackers] syncing newly created addres.pdb with addressbook
so to do what I want seems to be to write a conduit which dumps an
AddressDB from the Palm modifies it appropriately (e.g. Palm::Address...)
and fetches it back into the handheld. AM I correct here? Is there some
code (fragment maybe) out there to show me how to do this - my perl is only
a couple of days old :-)
cheers,
Ralf
