"""Parameters:
- (string) global_perm:
a series of letters referencing the users permissions;
defaults to "elradfmw" which means full read and write
access for everybody (except anonymous).
- (list) allowed_users:
a list of users which are accepted for authenticating
against the FTP server; defaults to [] (no restrictions).
- (list) rejected_users:
a list of users which are not accepted for authenticating
against the FTP server; defaults to [] (no restrictions).
- (bool) require_valid_shell:
Deny access for those users which do not have a valid shell
binary listed in /etc/shells.
If /etc/shells cannot be found this is a no-op.
Anonymous user is not subject to this option, and is free
to not have a valid shell defined.
Defaults to True (a valid shell is required for login).
- (string) anonymous_user:
specify it if you intend to provide anonymous access.
The value expected is a string representing the system user
to use for managing anonymous sessions; defaults to None
(anonymous access disabled).
- (string) msg_login:
the string sent when client logs in.
- (string) msg_quit:
the string sent when client quits.
