even realize what they are doing wrong.
Because they have not worked directly with the framework they don't
understand the framework . But YMMV

It imports os and sys only, they are standard library modules.
If you have python you have them already.
If you mean cStringIO it is in the standard library(at least on my

You dont have to use it just feed shlex an open file.
py>lexer = shlex.shlex(open('myrecord.txt
chars += '-' # add the hyphen
py>a.get_token()
'moo'
py>a.get_token()
'cow'
py>a.get_token()
'"farmer john"'
py>a.get_token()
'-zug'
py>a.get_token()
''
