This project objective consists on recreating some functionalities of [`wget`](https://www.gnu.org/software/wget/manual/wget.html) using **Go**

This flag should accept different value types, example: k and M. So you can put the rate limit as `rate-limit=200k` or `rate-limit=2M`

Example: `http://www.example.com`, the folder name will be `www.example.com` containing every file from the mirrored website. The flag should be `--mirror`.
To mirror a website you will have to implement the following `wget` flags so that the web mirror is complete (you do not need to do the literal flags, but just the theory behind it, so your flag `--mirror` need to behave like the following wget flags combined):
- [`--mirror`](https://www.gnu.org/software/wget/manual/wget.html) download recursive
- [`--convert-links`](https://www.gnu.org/software/wget/manual/wget.html), after the download is complete it will convert all links in the document to make them suitable for local viewing
- [`--page-requisites`](https://www.gnu.org/software/wget/manual/wget.html), downloads all files that are necessary to properly display a given HTML page
- [`--no-parent`](https://www.gnu.org/software/wget/manual/wget.html), this will not let the program ascend to the parent directory when retrieving
### Hint
You can take a look into the [html package](https://godoc.org/golang.org/x/net/html) for some help
