cat <<"USAGE"

Usage: vhost [OPTIONS] <name>
	-h|--help	this screen
	-pub		to create the webhost root in ~/www/name/public/
	-url 		to specify a local address, default is http://name.local
	-rm 		to remove a previously created vhost, see examples
	-d 		to specify the webroot directory location, default is in ~/www (NO TRAILING SLASH)
	-email 		to specify the email of the administrator in the virtual host file
	-l 		to list the current virtual hosts

IMPORTANT Notes:
1- You need git setup to grab the template file if you do not have it already.
2- You need to make sure you do not have a vhost called 'template' or that it is the one from this gist: https://gist.github.com/gistwebdev/5640113
3- Check your version of sed, you need to make sure -i works. GNU sed is suggested.

Examples:
vhost mysite                                                    this will create a new apache2 vhost named mysite with a webroot of ~/www/mysite/ reachable at http://mysite.local
vhost -pub mysite                                               this will create a new apache2 vhost named mysite with a webroot of ~/www/mysite/public/ reachable at http://mysite.local
vhost -d ~/sites/mysite/myroot -url dev.mysite.dev mysite       this will create a new apache2 vhost named mysite with a webroot of ~/sites/mysite/myroot reachable at http://dev.mysite.dev
vhost -rm mysite.local mysite                                   this will remove the apache2 vhost named mysite and remove the mysite.local entry from the /etc/hosts file. Be sure to specify boths
