arguments module should print to stderr #4

Closed kwkroll32 closed 8 years ago

kwkroll32 commented 8 years ago

I received an "incorrect usage" error while piping my output to stdout, but the error message ended up in my output file. Since stdout is (optionally) the path of our desired, fastq output, error and usage messages should be routed to stderr.

app.Writer is an io.Writer , just set it to os.Stderr
