    UsageLine: "go run [build flags] [-exec xprog] package [arguments...]",
    Short:     "compile and run Go program",
    Long: `
Run compiles and runs the named main Go package.
Typically the package is specified as a list of .go source files from a single directory,
but it may also be an import path, file system path, or pattern
matching a single known package, as in 'go run .' or 'go run my/cmd'.

By default, 'go run' runs the compiled binary directly: 'a.out arguments...'.
If the -exec flag is given, 'go run' invokes the binary using xprog:
    'xprog a.out arguments...'.
If the -exec flag is not given, GOOS or GOARCH is different from the system
default, and a program named go_$GOOS_$GOARCH_exec can be found
on the current search path, 'go run' invokes the binary using that program,
for example 'go_js_wasm_exec a.out arguments...'. This allows execution of
cross-compiled programs when a simulator or other execution method is
available.

The exit status of Run is not the exit status of the compiled binary.
