Additionally, a few wildcard release strings are also supported:

### Output prefixing
|

|

Xgo by default uses the name of the package being cross compiled as the output
|

file prefix. This can be overridden with the `-out` flag.

### Build flags
|
||||
|
||||
A handful of flags can be passed to `go build`. The currently supported ones are
|
||||
|
||||
- `-v`: prints the names of packages as they are compiled
|
||||
- `-race`: enables data race detection (supported only on amd64, rest built without)
