// This program can be used as go_ios_$GOARCH_exec by the Go tool.
// It executes binaries on an iOS device using the XCode toolchain
// and the ios-deploy program: https://github.com/phonegap/ios-deploy
//
// This script supports an extra flag, -lldb, that pauses execution
// just before the main program begins and allows the user to control
// the remote lldb session. This flag is appended to the end of the
// script's arguments and is not passed through to the underlying
// binary.
//
// This script requires that three environment variables be set:
// GOIOS_DEV_ID: The codesigning developer id or certificate identifier
// GOIOS_APP_ID: The provisioning app id prefix. Must support wildcard app ids.
// GOIOS_TEAM_ID: The team id that owns the app id prefix.
// $GOROOT/misc/ios contains a script, detect.go, that attempts to autodetect these.
