* plugins.d/mandos-client.c (main): Use remove() instead of unlink(),

134
      brings up a network interface, uses the interface’s IPv6
135
      link-local address to get network connectivity, uses Zeroconf to
136
      find servers on the local network, and communicates with servers
137
      using TLS with an OpenPGP key to ensure authenticity and
138
      confidentiality.  This client program keeps running, trying all
139
      servers on the network, until it receives a satisfactory reply

      To use this program for its intended purpose (see <xref

498
      have to be given out to be stored in a server computer, after
499
      having been encrypted using an OpenPGP key.  This encrypted data
500
      which will be stored in a server can only be decrypted by the
501
      OpenPGP key, and the data will only be given out to those
502
      clients who can prove they actually have that key.  This key,
503
      however, is stored unencrypted on the client side in its initial
