Browse Source 
Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.

==============
NAME
----
perf-annotate - Read perf.data (created by perf record) and display annotated code
SYNOPSIS
--------
[verse]
'perf annotate' [-i <file> | --input=file] symbol_name
DESCRIPTION
-----------
This command reads the input file and displays an annotated version of the
code. If the object file has debug symbols then the source code will be
displayed alongside assembly code.
If there is no debug info in the object, then annotated assembly is displayed.
OPTIONS
-------

Input file name. (default: perf.data)

perf-help(1)
============
NAME
----
perf-help - display help information about perf
SYNOPSIS
--------
'perf help' [-a|--all] [COMMAND]
DESCRIPTION
-----------
With no options and no COMMAND given, the synopsis of the 'perf'
command and a list of the most commonly used perf commands are printed
on the standard output.
If the option '--all' or '-a' is given, then all available commands are
printed on the standard output.
If a perf command is named, a manual page for that command is brought
up. The 'man' program is used by default for this purpose, but this
can be overridden by other options or configuration variables.
Note that `perf --help ...` is identical to `perf help ...` because the
former is internally converted into the latter.
OPTIONS
-------
-a::
--all::
Prints all the available commands on the standard output. This
option supersedes any other option.
