# == Define: openvpn::client
#
# This define creates the client certs for a specified openvpn server as well
# as creating a tarball that can be directly imported into openvpn clients
#
#
# === Parameters
#
# [*server*]
# String. Name of the corresponding openvpn endpoint
# Required
#
# [*compression*]
# String. Which compression algorithim to use
# Default: comp-lzo
# Options: comp-lzo or '' (disable compression)
#
# [*dev*]
# String. Device method
# Default: tun
# Options: tun (routed connections), tap (bridged connections)
#
# [*mute*]
# Integer. Set log mute level
# Default: 20
#
# [*mute_replay_warnings*]
# Boolean. Silence duplicate packet warnings (common on wireless networks)
# Default: true
#
# [*nobind*]
# Boolean. Whether or not to bind to a specific port number
# Default: true
#
# [*persist_key*]
# Boolean. Try to retain access to resources that may be unavailable
# because of privilege downgrades
# Default: true
#
# [*persist_tun*]
# Boolean. Try to retain access to resources that may be unavailable
# because of privilege downgrades
# Default: true
#
# [*port*]
# Integer. The port the openvpn server service is running on

# the server's hostname
# Default: infinite
# Options: Integer or infinite
#
# [*verb*]
# Integer. Level of logging verbosity
# Default: 3
#
#
# === Examples
