寫了個小工具，為了讓它看起來更專業(yè)一些，也很想讓工具能象Linux中的其它工具一樣能被man顯示使用它的幫助信息。上網(wǎng)搜了下相關(guān)的資料，網(wǎng)上找到了一些關(guān)于寫man幫助的語法，介紹得比較詳細和深入。同樣也得花許多時間來學(xué)習(xí)和掌握，我們的程序不需要更加表現(xiàn)豐富的幫助頁。我希望能花很少的時間快速寫出一個幫助來，所以我找到begin linux programing中的第九章中的幫助示例。以這個示例為基礎(chǔ)作些改動就可以作出一個還不錯的幫助頁，減少難度。

.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.
