The GOOS and GOARCH environment variables set the desired target.

Flags:

	-D name[=value]
		Predefine symbol name with an optional simple value.
		Can be repeated to define multiple symbols.
	-I dir1 -I dir2
		Search for #include files in dir1, dir2, etc,
		after consulting $GOROOT/pkg/$GOOS_$GOARCH.
	-S
		Print assembly and machine code.
	-V
		Print assembler version and exit.
	-debug
		Dump instructions as they are parsed.

This document explains the design, architecture and advanced use cases of the MinIO distributed server.

## Command-line

```
NAME:
  minio server - start object storage server

USAGE:
  minio server [FLAGS] DIR1 [DIR2..]
