-# String globbing in Go
-
-[![GoDoc](https://godoc.org/github.com/zyedidia/glob?status.svg)](http://godoc.org/github.com/zyedidia/glob)
-
-This package adds support for globs in Go.
-
-It simply converts glob expressions to regexps. I try to follow the standard defined [here](http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_13).
-
-# Example
-
-```go
-package main
-
-import "github.com/zyedidia/glob"
-
-func main() {
-    glob, err := glob.Compile("{*.go,*.c}")
-    if err != nil {
-        // Error
-    }
-
-    glob.Match([]byte("test.c"))   // true
-    glob.Match([]byte("hello.go")) // true
-    glob.Match([]byte("test.d"))   // false
-}
-```
-
-You can call all the same functions on a glob that you can call on a regexp.
