zescrow-client binary package in Ubuntu Precise powerpc

 zescrow-client provides the zescrow (formerly ecryptfs-escrow-private) utility,
 which can be used to upload a backup of an eCryptfs
 Encrypted Home or eCryptfs Encrypted Private configuration
 to a zEscrow compatible server.
 .
 zEscrow.gazzang.com is one such compatible server, an implementation
 of the AGPL free software available at https://launchpad.net/zEscrow.
 .
 zEscrow will:
  - prompt for your chosen zEscrow server
  - retrieve the public GPG key of that zEscrow server
  - prompt for your login passphrase
  - use your login passphrase to decrypt your mount passphrase
  - create a tar archive of your ~/.ecryptfs directory and decrypted
    mount passphrase
  - gpg encrypt that archive the your zEscrow server's public key
  - upload your encrypted archive to your zEscrow server
  - display a URL and offer to launch a browser, where you must go
    to associate a Google account and email address with your backup
