Collect the
stdout of the process. If used, the
stdout will not be echoed to the terminal, unless you include
EchoStdout. The value type may be either
String, or
either lazy or strict
ByteString.
Note that most programs end their output with a trailing newline, so
calling
ghc --numeric-version will result in
Stdout of
"6.8.3\n". If you want to automatically trim the resulting
string, see
StdoutTrim.
