Regular users do not need to execute it.

			Description: `

    get wallet import /path/to/my/presale.wallet

will prompt for your password and imports your ether presale account.
It can be used non-interactively with the --password option taking a
passwordfile as argument containing the wallet password in plaintext.

`},
		{
			Action: accountList,
			Name:   "account",
			Usage:  "manage accounts",
			Description: `

Manage accounts lets you create new accounts, list all existing accounts,
import a private key into a new account.

'            help' shows a list of subcommands or help for one subcommand.

It supports interactive mode, when you are prompted for password as well as
non-interactive mode where passwords are supplied via a given password file.
Non-interactive mode is only meant for scripted use on test networks or known
safe environments.

Make sure you remember the password you gave when creating a new account (with
either new or import). Without it you are not able to unlock your account.

Note that exporting your key in unencrypted format is NOT supported.

Keys are stored under <DATADIR>/keys.
It is safe to transfer the entire directory or the individual keys therein
between ethereum nodes by simply copying.
Make sure you backup your keys regularly.

In order to use your account to send transactions, you need to unlock them using the
'--unlock' option. The argument is a comma

And finally. DO NOT FORGET YOUR PASSWORD.
