26 | Babeltrace is a trace viewer and converter reading and writing the | |
27 | Common Trace Format (CTF). Its main use is to pretty-print CTF | |
28 | traces into a human-readable text output. | |
29 | ||
74ea15ad | 30 | To use this module, the first step is to create a TraceCollection and add a |
