Missing list of dependancies in example

[haddow777]

Hello. I will admit I am quite new to Rust and so am not familiar with much. I wanted some logging functionality and this library looked good. On the main readme page, there is a link to cmd-program.rs and so I added it to a file to play around with. Unfortunately, it comes up with an error on almost every line as it seems the example code is extremely dependant on other libraries for its functionality.
I've so far managed to piece together exactly which libraries to hunt down and install just to get the example to work, but it seems to me that it would be a lot more helpful to those of us who are new to Rust to have a commented list of library dependancies used in the example code so we don't have to work so hard just to get an example running.
I guess, for anyone who's been working in Rust for any meaningful amount of time, they may likely be familiar with all the libraries used. Still, it would be nice if such lists could be added to the top of the example files for those of us less experienced.
Thank you for your time.

Okay, there may be more going on with that example than my inexperience bungling things. I've managed to find and install all the libraries the compiler is complaining are missing and yet the file still has errors. Mainly now, the library Clap doesn't appear to be in line with the code. When I go the the site that lists all Cargo libraries and look up Clap, there is no reference to a clap::App struct at all. I've google around and found references in other places, but as the Cargo site is showing what gets installed, I'm guessing clap::App must be from a fork or is from an old outdated version.
I'm not going to push it as this is already way too much of a headache for what should be a drop in example. I just thought I would let you know that it isn't working. There may still be a good chance I'm bungling something with my noobishness, but then, if a noob can't trust an example to help them understand things, it may not be a great example.
Again, thanks for your time.

That's a good call! The fern example are indeed using clap 2.0.0, while the latest version is clap 4. I should definitely update that.
