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 memoir
and pgfmanual
are superb examples of documentation.
