`pttree` is designed to give a quick overview of the contents of a PyTables HDF5 file by printing
a depth-indented list of nodes, similar to the output of the Unix `tree` function. It can also
display the size, shape and compression states of individual nodes, as well as summary information
for the whole file. For a more verbose output (including metadata), see `ptdump`.

positional arguments:
  filename[:nodepath]   path to the root of the tree structure

options:
  -h, --help            show this help message and exit
  -L MAX_DEPTH, --max-level MAX_DEPTH
                        maximum branch depth of tree to display (-1 == no limit)
  -S SORT_BY, --sort-by SORT_BY
                        artificially order nodes, can be either "size", "name" or "none"
  --print-size          print size of each node/branch
  --no-print-size
  --print-shape         print shape of each node
  --no-print-shape
  --print-compression   print compression library(level) for each compressed node
  --no-print-compression
  --print-percent       print size of each node as a % of the total tree size on disk
  --no-print-percent
  --use-si-units        report sizes in SI units (1 MB == 10^6 B)
  --use-binary-units    report sizes in binary units (1 MiB == 2^20 B)
