Iterable as input:

>> with open('simplerun.py') as f:
>>    r = simplerun.run('grep def', f)
>>    print(r.std_out)

Result as input:

>> r_data = simplerun.run('ps aux')
>> r = simplerun.run('grep Chrome', r_data)

Debugger:

>> r = run('ps aux | stranger | grep keyword')
>> r
<[-1] `stranger`>
>> r.exc
OSError(2, 'No such file or directory')

Found the stanger is the evil

>> r.history
[<[0] `ps aux`>]

Show history, and run it again with good input:

>> r.rest
[['grep', 'keyword']]
>>
>> r2 = run(r.rest, '''This is the good line that contains the keyword
                       but not this line, sorry.''')
>> r2
<[0] `grep keyword`>
>> print(r2.std_out)
'This is a good line that contains the keyword\n'

Concurrent & Parallel:

>> batches = ['ps', 'top -n 10', 'uptime']
>> r = prun(batches)
>> r2 = crun(batches)
