写了个小工具，为了让它看起来更专业一些，也很想让工具能象Linux中的其它工具一样能被man显示使用它的帮助信息。上网搜了下相关的资料，网上找到了一些关于写man帮助的语法，介绍得比较详细和深入。同样也得花许多时间来学习和掌握，我们的程序不需要更加表现丰富的帮助页。我希望能花很少的时间快速写出一个帮助来，所以我找到begin linux programing中的第九章中的帮助示例。以这个示例为基础作些改动就可以作出一个还不错的帮助页，减少难度。
.TH MYAPP 1
.SH NAME
Myapp \- A simple demonstration application that does very little.
.SH SYNOPSIS
.B myapp
[\-option ...]
.SH DESCRIPTION
.PP
\fImyapp\fP is a complete application that does nothing useful.
.PP
It was written for demonstration purposes.
.SH OPTIONS
.PP
It doesn't have any, but lets pretend, to make this template complete:
.TP
.BI \-option
If there was an option, it would not be -option.
.SH RESOURCES
.PP
myapp uses almost no resources.
.SH DIAGNOSTICS
The program shouldn't output anything, so if you find it doing so there's
probably something wrong. The return value is zero.
.SH SEE ALSO
The only other program we know with this this little functionality is the
ubiquitous hello world application.
