+### Embedded structs
+
+The fields of embedded structs are treated just like regular fields:
+
+```go
+
+type DatabaseOptions struct {
+ Host string
+ Username string
+ Password string
+}
+
+type LogOptions struct {
+ LogFile string
+ Verbose bool
+}
+
+func main() {
+ var args struct {
+ DatabaseOptions
+ LogOptions
+ }
+ arg.MustParse(&args)
+}
+```
+
+As usual, any field tagged with `arg:"-"` is ignored.

### Custom parsing
You can implement your own argument parser by implementing `encoding.TextUnmarshaler`:
