+usage: cairo-trace [--no-file] command
+cairo-trace will generate a log of all calls made by command to
+cairo. This log will be stored in a file in the local directory
+called command.pid.trace.
+Whatever else happens is driven by its argument:
+  --flush         - Flush the output trace after every call.
+  --no-file       - Disable the creation of an output file. Outputs to the
+                    terminal instead.
+  --no-callers    - Do not lookup the caller address/symbol/line whilst tracing.
+  --mark-dirty    - Record image data for cairo_mark_dirty() [default]
+  --no-mark-dirty - Do not record image data for cairo_mark_dirty()
+  --compress      - Compress the output with LZMA
+  --profile       - Combine --no-callers and --no-mark-dirty and --compress
+
+Environment variables understood by cairo-trace:
+  CAIRO_TRACE_FLUSH - flush the output after every function call.
+  CAIRO_TRACE_LINE_INFO - emit line information for most function calls.
