+Fmt runs the command 'gofmt -l -w' on the packages named
+by the import paths.  It prints the names of the files that are modified.

+For more about gofmt, see 'godoc gofmt'.
+For more about specifying packages, see 'go help packages'.
+
+The -n flag prints commands that would be executed.
+The -x flag prints commands as they are executed.
+
+To run gofmt with specific options, run gofmt itself.

+See also: go fix, go vet.
