Package shlex implements a simple lexer which splits input in to tokens using
shell-style rules for quoting and commenting.
The basic use case uses the default ASCII lexer to split a string into sub-strings:
shlex.Split("one \"two three\" four") -> []string{"one", "two three", "four"}
To process a stream of strings:
l := NewLexer(os.Stdin)
for ; token, err := l.Next(); err != nil {
// process token
}
To access the raw token stream (which includes tokens for comments):
t := NewTokenizer(os.Stdin)
for ; token, err := t.Next(); err != nil {
// process token
}

### Redhat / CentOS
Redhat / CentOS builds have been known to fail with the following error due to `sftp_command`, which should be set to `/usr/libexec/openssh/sftp-server -e`:
```
==> virtualbox-ovf: starting sftp subsystem

```
### winrm communicator
Windows builds require a custom Ansible communicator and a particular configuration. Assuming a directory named `connection_plugins` is next to the playbook and contains a file named `packer.py` whose contents is
```
from __future__ import (absolute_import, division, print_function)
__metaclass__ = type
from ansible.plugins.connection.ssh import Connection as SSHConnection
class Connection(SSHConnection):
''' ssh based connections for powershell via packer'''
transport = 'packer'

become_methods = []
allow_executable = False
module_implementation_preferences = ('.ps1', '')
def __init__(self, *args, **kwargs):
super(Connection, self).__init__(*args, **kwargs)
