Usage

Synchronous output

Create an external command with a builder and spawn a child process or wait for the output. Then get the output status, stdout or stderr:

output := GtExternalProcessBuilder new
   command: 'ls';
   arg: '-la';
   output.
	
output stdoutString

Buffered non-blocking IO

Pipe the stdout or stderr and poll regularly from an asynchronousStdout:

child := GtExternalProcessBuilder new
   command: 'ping';
   arg: 'google.com';
   pipeStdout;
   spawn.

child asynchronousStdout
   pollStringEvery: 1 second
   do: [ :aString | aString trace ].
