This chapter describes various Info commands for experts. (If you are using a stand-alone Info reader, there are additional commands specific to it, which are documented in several chapters of GNU Info.)
This chapter also explains how to write an Info as distinct from a Texinfo file. (However, in most cases, writing a Texinfo file is better, since you can use it to make a printed manual or produce other formats, such as HTML and DocBook, as well as for generating Info files.) See Overview of Texinfo.)
