  14 usage: cairo-trace [--no-file] command
  15 cairo-trace will generate a log of all calls made by command to
  16 cairo. This log will be stored in a file in the local directory
  17 called command.pid.trace.
  18 Whatever else happens is driven by its argument:
  19   --flush         - Flush the output trace after every call.
  20   --no-file       - Disable the creation of an output file. Outputs to the
  21                     terminal instead.
  22   --no-callers    - Do not lookup the caller address/symbol/line whilst tracing.
  23   --mark-dirty    - Record image data for cairo_mark_dirty() [default]
  24   --no-mark-dirty - Do not record image data for cairo_mark_dirty()
  25   --compress      - Compress the output with LZMA
  26   --profile       - Combine --no-callers and --no-mark-dirty and --compress

  28 Environment variables understood by cairo-trace:
  29   CAIRO_TRACE_FLUSH - flush the output after every function call.
  30   CAIRO_TRACE_LINE_INFO - emit line information for most function calls.
