I am reading the
texdoc for the
letter document class. But it doesn't say anything about getting started. I think this is a commented source code document. Yes, it lists all the features of the
letter class, but it doesn't say anything about how to use them in practice. There is no tutorial or walkthrough or something similar. To illustrate what I mean:
This question is related to the one I asked about reading commented sources. I noticed that most documentation is in this form, which is rather frustrating. In contrast, the
pgfmanual are superb examples of documentation.
