+# String globbing in golang [![Build Status](https://travis-ci.org/ryanuber/go-glob.svg)](https://travis-ci.org/ryanuber/go-glob)
+
+`go-glob` is a single-function library implementing basic string glob support.
+
+Globs are an extremely user-friendly way of supporting string matching without
+requiring knowledge of regular expressions or Go's particular regex engine. Most
+people understand that if you put a `*` character somewhere in a string, it is
+treated as a wildcard. Surprisingly, this functionality isn't found in Go's
+standard library, except for `path.Match`, which is intended to be used while
+comparing paths (not arbitrary strings), and contains specialized logic for this
+use case. A better solution might be a POSIX basic (non-ERE) regular expression
+engine for Go, which doesn't exist currently.
+
+Example
+=======
+
+```
+package main
+
+import "github.com/ryanuber/go-glob"
+
+func main() {
+    glob.Glob("*World!", "Hello, World!") // true
+    glob.Glob("Hello,*", "Hello, World!") // true
+    glob.Glob("*ello,*", "Hello, World!") // true
+    glob.Glob("World!", "Hello, World!")  // false
+    glob.Glob("/home/*", "/home/ryanuber/.bashrc") // true
+}
+```
