-=========
-
-Package paginater is a helper module for custom pagination calculation.
-
-## Installation
-
-	go get github.com/Unknwon/paginater
-
-## Getting Started
-
-The following code shows an example of how to use paginater:
-
-```go
-package main
-
-import "github.com/Unknwon/paginater"
-
-func main() {
-	// Arguments:
-	// - Total number of rows
-	// - Number of rows in one page
-	// - Current page number 
-	// - Number of page links
-	p := paginater.New(45, 10, 3, 3)
-	
-	// Then use p as a template object named "Page" in "demo.html"
-	// ...
-}
-```
-
-`demo.html`
-
-```html
-{{if not .Page.IsFirst}}[First](1){{end}}
-{{if .Page.HasPrevious}}[Previous]({{.Page.Previous}}){{end}}
-
-{{range .Page.Pages}}
-	{{if eq .Num -1}}
-	...
-	{{else}}
-	{{.Num}}{{if .IsCurrent}}(current){{end}}
-	{{end}}
-{{end}}
-
-{{if .Page.HasNext}}[Next]({{.Page.Next}}){{end}}
-{{if not .Page.IsLast}}[Last]({{.Page.TotalPages}}){{end}}
-```
-
-Possible output:
-
-```
-[First](1) [Previous](2) ... 2 3(current) 4 ... [Next](4) [Last](5)
-```
-
-As you may guess, if the `Page` value is `-1`, you should print `...` in the HTML as common practice.
