# Description:
# Verify that compressed send works correctly with incremental sends.
#
# Strategy:
# 1. Randomly choose either a -i or -I incremental.
# 2. Generate compressed incremental replication streams for a pool, a
#    descendant dataset, and a volume.
# 3. Receive these streams verifying both the contents, and intermediate
#    snapshots are present or absent as appropriate to the -i or -I option.
