// Antimony (sb51) is a Syncbase general-purpose client and management utility.
// It currently supports experimenting with the Syncbase query language.
//
// The 'sh' command connects to a specified database on a Syncbase instance,
// creating it if it does not exist if -create-missing is specified.
// The user can then enter the following at the command line:
//     1. dump - to get a dump of the database
//     2. a syncbase select statement - which is executed and results printed to stdout
//     3. make-demo - to create demo tables in the database to experiment with, equivalent to -make-demo flag
//     4. exit (or quit) - to exit the program
//
// When the shell is running non-interactively (stdin not connected to a tty),
// errors cause the shell to exit with a non-zero status.
//
// To build client:
//     jiri go install v.io/x/ref/cmd/sb51
//
// To run client:
//     $JIRI_ROOT/release/go/bin/sb51 sh <appname> <dbname>
//
// Sample run (assuming a syncbase service is mounted at '/:8101/syncbase',
// otherwise specify using -service flag):
//     > $JIRI_ROOT/release/go/bin/sb51 sh -create-missing -make-demo -format=csv demoapp demodb

//     ? select v.CustId, v.InvoiceNum, v.ShipTo.Zip, v.Amount from Customers where Type(v) = "Invoice" and v.Amount > 100;
