gnats-user binary package in Ubuntu Trusty arm64

 GNATS is a bug-tracking tool designed for use at a central "Support
 Site". Users who experience problems use electronic mail to
 communicate these problems to "maintainers" at that Support Site.
 .
 GNATS offers many of the same features offered by more generalized
 databases, including editing, querying, and basic reporting. You can
 access the submitting, editing, and querying functions of GNATS
 through provided utilities or from within GNU Emacs.
 .
 The "gnats-user" package has just the user tools for client machines.
 For the full installation and the central database server use the
 "gnats" package.
 .
 If you prefer not to use either an nfs-mounted database or the client/server
 model, it is possible to make a distribution that works entirely over e-mail.
 For more information, see gnats-info and type 'g' (for goto) followed by
 'mkdist'. This package is not necessary for email-only setups.
