-- Script out indexes completely, including both PK's and regular indexes, each clustered or nonclustered.
-- DOES NOT HANDLE COMPRESSION; that's ok, since 2008 R2 RTM benchmarking shows it's faster and results in smaller indexes to insert uncompressed and then compress later
-- HARDCODES [dbo] schema (i.e. it doesn't say [JohnDoe].[table], changing that to [dbo].[table]
