trivial zephyr client

## NAME

tzc - trivial zephyr client

## SYNOPSIS

**tzc** \[*options*\]

## DESCRIPTION

**Tzc** is a zephyr client program which talks to the zephyr servers (via the "zephyr host manager") and to a gnu-emacs running zephyr-mode.

## OPTIONS

A summary of options is included below.

- **-a** *nseconds*

  Restart tzc every  *nseconds* seconds.

- **-e** *exposure*

  Set exposure.  (values: NONE, OPSTAFF, REALM-VISIBLE, REALM-ANNOUNCED,  NET-VISIBLE, NET-ANNOUNCED)

- **-l,** *location*

  Set zlocation tty to the string *location*. The default is tzc.n, where n is tzc's pid.
