Design

Because I didn't know how to write this code at the begginning, so I just imitated the source code selpg.c, So I didn't use so many functions, which may let you see some awful. So some details of the code will be not described here.

We can see the files in the project:
-the selpg.go is the source code.
-the outputx.txt is the file to output the pages
-the testx.txt is the "inputFile" I use
-the errorx.txt is the stderr that may be printed

Here are some command(I forgot to use the $GOPATH/bin)
