  22 # Description:
  23 # Verify that compressed streams can contain embedded blocks.
  24 #
  25 # Strategy:
  26 # 1. Create a filesystem with compressible data and embedded blocks.
  27 # 2. Verify the created streams can be received correctly.
  28 # 3. Verify the presence / absence of embedded blocks in the compressed stream,
  29 #    as well as the receiving file system.
