A call to oft2-print has the following syntax:
Usage: otf2-print [OPTION]... [--] ANCHORFILE
Print selected content of the OTF2 archive specified by ANCHORFILE.

Options:
  -A, --show-all          print all output including definitions and anchor
                          file
  -G, --show-global-defs  print all global definitions
  -I, --show-info         print information from the anchor file
  -T, --show-thumbnails   print the headers from all thumbnails
  -M, --show-mappings     print mappings to global definitions
  -C, --show-clock-offsets
                          print clock offsets to global timer
      --timestamps=<FORMAT>
                          format of the timestamps. <FORMAT> is one of:
                           plain -  no formatting is done (default)
                           offset - timestamps are relative to the global offset
                                    (taken form the ClockProperties definition)
  -L, --location <LID>    limit output to location <LID>
  -s, --step <N>          step through output by steps of <N> events
      --time <MIN> <MAX>  limit output to events within time interval
      --system-tree       output system tree to dot-file
      --silent            only validate trace and do not print any events
      --unwind-calling-context
                          unwind the calling context for each calling context
                          event. Each calling context node is prefixed depending
                          on the unwind distance of the current event:
                           '?' - unwind distance is undefined
                           '+' - region was newly entered
                           '*' - region was not left
                           ' ' - region did not made any progress
  -Werror, --warnings-as-errors
                          all warnings are treated as errors
  -d, --debug             turn on debug mode
  -V, --version           print version information
  -h, --help              print this help information
