Make sure it works in Mac

We might have to use ttyrec to do so. Check shelr for an example.

I'm looking into this. It's funny that script on mac does not have -f and -t does something different.

NAME
     script -- make typescript of terminal session

SYNOPSIS
     script [-akq] [-t time] [file [command ...]]

DESCRIPTION
     The script utility makes a typescript of everything printed on your ter-
     minal.  It is useful for students who need a hardcopy record of an
     interactive session as proof of an assignment, as the typescript file
     can be printed out later with lpr(1).

     If the argument file is given, script saves all dialogue in file.  If no
     file name is given, the typescript is saved in the file typescript.

     If the argument command is given, script will run the specified command
     with an optional argument vector instead of an interactive shell.

     The following options are available:

     -a      Append the output to file or typescript, retaining the prior
             contents.

     -k      Log keys sent to program as well as output.

     -q      Run in quiet mode, omit the start and stop status messages.

     -t time
             Specify time interval between flushing script output file.  A
             value of 0 causes script to flush for every character I/O event.
             The default interval is 30 seconds.

Should be something like

if platform.system() == 'Darwin':
    shell_args = '-qt 0'
else:
    shell_args = '-qf'

os.system('script %s %s' % (shell_args, filename))

Okay, apparently there is a difference in the way files are read. On mac, I can't get the additional content with open(). I'll look into proper pipes. Unless we can solve #2. However, I'm not entirely sure how this is going to work.
