[Proposal]Add a 'typical usage' section to man pages

[A. Z. Rick]

Hi, all

The Manpages is the de facto standard way to get info about
commands and other things. It often helps, but it also has some weak
point. A typical man page can be long, more than 300 lines, and cover
many aspects of the commands(or other things). But the user often
need only the info to write a command line for typical usage. It is a
pain in the ass to scan nnn line man page to write only one command
line. And such pain happens again and again...

Let us add a 'typical usage' section to man pages. In this 'typical usage'
section, we will put the command lines for most typical usage and their
short explanations in it. A search engine may help us judge which usage
is the 'most typical usage'.

Any comments?
