Queries can be made via `lookup`. The format is described in OpenSSH's ``ssh_config`` man page.

This class introduces some usage niceties for consumers of `SSHConfig`, specifically around the issue of variable type conversions: normal value access yields strings, but there are now methods such as `as_bool` and `as_int` that yield casted values instead. For example, given the following ``ssh_config`` file snippet:: Host foo.example.com PasswordAuthentication no Compression yes ServerAliveInterval 60 the following code highlights how you can access the raw strings as well as usefully Python type-casted versions (recalling that keys are all normalized to lowercase first):: my_config = SSHConfig() my_config.parse(open('~/.ssh/config')) conf = my_config.lookup('foo.example.com') assert conf['passwordauthentication'] == 'no' assert conf.as_bool('passwordauthentication') is False assert conf['compression'] == 'yes' assert conf.as_bool('compression') is True assert conf['serveraliveinterval'] == '60' assert conf.as_int('serveraliveinterval') == 60 .. versionadded:: 2.5 cp||}t|tr|S|dkS)a Express given key's value as a boolean type. Typically, this is used for ``ssh_config``'s pseudo-boolean values which are either ``"yes"`` or ``"no"``.
