  22 # Description:
  23 # Verify compression features show up in zstreamdump
  24 #
  25 # Strategy:
  26 # 1. Create a full compressed send stream
  27 # 2. Verify zstreamdump shows this stream has the relevant features
  28 # 3. Verify zstreamdump's accounting of logical and compressed size is correct
  29 #
