+# 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.
