caja-sendto binary package in Ubuntu Xenial i386

 Caja is the official file manager for the MATE desktop. This
 package adds extended functionality to the Caja file manager.

 The Caja Send To extension provides the Caja file manager with a context
 menu component for quickly sending files to given email addresses, contacts
 on a Pidgin or Gajim instant messaging list, through Thunderbird/Icedove,
 or through Claws Mail.

 Caja Send To also provides the option of compressing the files (tar.bz2,
 tar.gz, or zip) before sending.
