I have a 13Mb vcf file and would love to split this into it's
component parts.

i.e. I want to have a seperate .vcf file for each addressee.

For those script experts that are unfamiliar with v-cards
it is a text file that looks like this.

BEGIN:VCARD
VERSION:3.0
N:LastName;FirstName;;;
FN:FirstName LastName
....
....
END:VCARD
BEGIN:VCARD
....

I'd like to have the seperate .vcf files named on the N field
with a syntax like: LastName-FirstName.vcf

Hope someone can give some hints to a script newbie.
