   Summary : Basic plugins for nbdkit
   Description :
   This package contains some basic plugins for nbdkit which have only
   trivial dependencies.

• nbdkit-data-plugin
  Serve small files directly from the command line.
• nbdkit-file-plugin
  A file serving plugin.
• nbdkit-memory-plugin
  A virtual memory plugin.
• nbdkit-nbd-plugin
  An NBD forwarding plugin.
  It provides an NBD server that forwards all traffic as a client to
  another existing NBD server. A primary usage of this setup is to
  alter the set of features available to the ultimate end client,
  without having to change the original server (for example, to
  convert between oldstyle and newtyle, or to add TLS support where
  the original server lacks it).
• nbdkit-null-plugin
  A null (bitbucket) plugin.
• nbdkit-pattern-plugin
  Fixed test pattern.
• nbdkit-random-plugin
  Random content plugin for testing.
• nbdkit-split-plugin
  Concatenate one or more files into a single virtual disk.
• nbdkit-streaming-plugin
  A streaming file serving plugin.
• nbdkit-zero-plugin
  Zero-length plugin for testing.
