perf has many undocumented options, such as:-vv, --exec-path, --html-path, -p, --paginate,--no-pager, --debugfs-dir, --buildid-dir, --list-cmds, --list-opts. Add entris for these options in perf.txt.

| DESCRIPTION
 | |
| -----------
 | |
| Performance counters for Linux are a new kernel-based subsystem
 | |
| that provide a framework for all things performance analysis. It
 | |
| covers hardware level (CPU/PMU, Performance Monitoring Unit) features
 | |
| and software features (software counters, tracepoints) as well.
