family - should be unix, inet, inet6 (default is unix if path is specified,
of inet if no path)
type - should be stream, dgram, raw, rdm or seqpacket (default is stream)
backlog - specifies the listen backlog (default is 5)
Options for family=unix
path - must be an absolute path (required)
umask - override the current umask when creating the socket file
Options for family=inet or family=inet6
port - if left out, the system will assign a port
interface - only bind to a single ethernet adaptor
host - you will usually want the default, which will be 127.0.0.1 if no
interface it specified and 0.0.0.0 otherwise
reuseport - on systems that support it, papa will create and bind a new
socket for each process that uses this socket
The url must start with "tcp:", "udp:" or "unix:".
Examples:
make socket uwsgi port=8080
make socket chaussette path=/tmp/chaussette.sock
