## profile() -- create a new profile

`profile(env, aln=None, **vars)`

> This creates a new `profile` object. By default, the profile is empty. However, if you give a single `alignment` object as an argument, the profile is initialized with the alignment contents (using alignment.to_profile()), or if you specify any keyword arguments, they are passed to profile.read(), to read in a profile from a file. See the profile.scan() example.
