Update the documentation to provide help about JSON output generation, and add an example in bpftool-prog manual page. Also reintroduce an example that was left aside when the tool was moved from GitHub to the kernel sources, in order to show how to mount the bpffs file system (to pin programs) inside the bpftool-prog manual page.

DESCRIPTION
|
|
===========
|
|
*bpftool* allows for inspection and simple modification of BPF objects
|
|
on the system.
|
|
|
|
Note that format of the output of all tools is not guaranteed to be
|
|
stable and should not be depended upon.
|
|
|
|
OPTIONS
|
|
=======
|
|
-h, --help
|
|
Print short help message (similar to **bpftool help**).
|
|
|
|
-v, --version
|
|
Print version number (similar to **bpftool version**).
|
|
|
|
-j, --json
|
|
Generate JSON output. For commands that cannot produce JSON, this
|
|
option has no effect.
|
|
|
|
-p, --pretty
|
|
Generate human-readable JSON output. Implies **-j**.
