netrc Objects
-------------
A `netrc' instance has the following methods:
`authenticators(host)'
Return a 3-tuple `(LOGIN, ACCOUNT, PASSWORD)' of authenticators
for HOST. If the netrc file did not contain an entry for the
given host, return the tuple associated with the `default' entry.
If neither matching host nor default entry is available, return
`None'.
`__repr__()'
Dump the class data as a string in the format of a netrc file.
(This discards comments and may reorder the entries.)
Instances of `netrc' have public instance variables:
`hosts'
Dictionary mapping host names to `(LOGIN, ACCOUNT, PASSWORD)'
tuples. The `default' entry, if any, is represented as a
pseudo-host by that name.
`macros'
Dictionary mapping macro names to string lists.
