 1 | Simplest file server to (temporarily) serve static content from a local filesystem.
 2 | 
 3 | Usage:
 4 | 
 5 |     fileserver [-a host:port] [pattern:]dir ...
 6 | 
 7 | The program serves files from a local dist using dir argument as root.
 8 | An optional pattern specified the URL base path. For instance,
 9 | to serve /tmp dir at /temporary, one can use the following:
10 | 
11 |     fileserver /temporary:/tmp
12 | 
13 | The dir argument can be specified multiple times.
14 | If no dir argument is provided, current directory is used.
15 | 
16 |   -a string
17 |     	Address (host:port) to listen on (default "localhost:8000")
