Preview features are not currently available to most Cloud Bigtable customers. Alpha
features might be changed in backward-incompatible ways and are not recommended
for production use. They are not subject to any SLA or deprecation policy.
Syntax rules for the Bash shell apply to the ` + "`cbt`" + ` CLI. This means, for example,
that you must put quotes around values that contain spaces or operators. It also means that
if a value is arbitrary bytes, you need to prefix it with a dollar sign and use single quotes.
Example:
cbt -project my-project -instance my-instance lookup my-table $'\224\257\312W\365:\205d\333\2471\315\'
For convenience, you can add values for the -project, -instance, -creds, -admin-endpoint and -data-endpoint
options to your ~/.cbtrc file in the following format:
project = my-project-123
instance = my-instance
creds = path-to-account-key.json
admin-endpoint = hostname:port
data-endpoint = hostname:port
auth-token = AJAvW039NO1nDcijk_J6_rFXG_...
timeout = 30s
All values are optional and can be overridden at the command prompt.

// const formatHelp = `
// ## Custom data formatting for the ` + "`" + `lookup` + "`" +
// ` and ` + "`" + `read` + "`" + ` commands.
// You can provide custom formatting information for formatting stored

// - ` + "`" + `BigEndian` + "`" + ` (aliases: ` + "`" + `BINARY` + "`" + `, ` +

// "`" + `P` + "`" + `)
// Encoding names and aliases are case insensitive.
// The Hex encoding is type agnostic. Data are displayed as a raw

// `float64` + "`" + `. Stored data length must be a multiple of the

// length matches the type size, or as arrays otherwise. Types names are case
// insensitive.
// The types given for the ` + "`" + `ProtocolBuffer` + "`" + ` encoding
// must case-insensitively match message types defined in provided

// defaults to the column name for the column data being displayed.
// Encoding and type are provided at the column level. Default encodings
// and types may be provided overall and at the column-family level. You
// don't need to define column formatting at the family level unless you
// have multiple column families and want to provide family-specific
// defaults or need to specify different formats for columns of the same
// name in different families.
// Protocol-buffer definition files may be given, as well as directories

// no paths are specified, then the current working directory is used.

const docIntroTemplate = `The ` + "`cbt`" + ` CLI is a command-line interface that lets you interact with Cloud Bigtable.
See the [cbt CLI overview](https://cloud.google.com/bigtable/docs/cbt-overview) to learn how to install the ` + "`cbt`" + ` CLI.
Before you use the ` + "`cbt`" + ` CLI, you should be familiar with the [Bigtable overview](https://cloud.google.com/bigtable/docs/overview).
The examples on this page use [sample data](https://cloud.google.com/bigtable/docs/using-filters#data) similar to data
that you might store in Bigtable.
Usage:
cbt [-<option> <option-argument>] <command> <required-argument> [optional-argument]
The commands are:
{{range .Commands}}
{{printf "%-25s %s" .Name .Desc}}{{end}}
The options are:
{{range .Flags}}
-{{.Name}} string
{{.Usage}}{{end}}
Example: cbt -instance=my-instance ls
Use "cbt help \<command>" for more information about a command.
