Creates an Apache VirtualHost config file based on some input (URL and document root) and adds the informed URL to the local /etc/hosts file.
You must run this with sudo since the script will create/edit files not owned by your user (probably).
PS: the code is bad, but it Just Works™ (at least on my machine ¯\(ツ)/¯ )
# Make it executable
$ sudo chmod +x mkvhost
# Fire!
$ sudo ./mkvhost
