@moderators Maybe this should be in Learning Rust :safe:

In safe_network/cli.rs at main lines 28 on

use clap::{AppSettings::ColoredHelp, Parser};
use color_eyre::{eyre::eyre, Result};
use sn_api::{Safe, XorUrlBase};
use std::path::PathBuf;
use tracing::{debug, warn};

Ok we are importing functions/code from else where - just what are we importing and why? some is obvious to me, some is not

line 34 has a useless (to me) comment after it

#[derive(clap::StructOpt, Debug)]
/// Interact with the Safe Network

Somebody ELIF that line #[derive(clap::StructOpt, Debug)] please? cos # is NOT a comment here AIUI

lines 49-57 deal with options on the command line

  /// Output data serialisation: [json, jsoncompact, yaml]
    #[clap(short = 'o', long = "output", global(true))]
    output_fmt: Option<OutputFmt>,
    /// Use JSON as output serialisation format (alias of '--output json')
    #[clap(long = "json", global(true))]
    output_json: bool,
    /// Base encoding for XOR-URLs. Currently supported: base32z (default), base32 and base64
    #[clap(long = "xorurl", global(true))]
    xorurl_base: Option<XorUrlBase>,

Why would I want to use any option other than the default? What are the use cases for the non-default options?
Just little stuff like that would certainly help me and possibly others too.
