+> Go Globbing Library.
+
+## Install
+
+```shell
+ go get github.com/gobwas/glob
+```
+
+## Example
+
+```go
+
+package main
+
+import "github.com/gobwas/glob"
+
+func main() {
+ var g glob.Glob
+
+ // create simple glob
+ g = glob.MustCompile("*.github.com")
+ g.Match("api.github.com") // true
+
+ // quote meta characters and then create simple glob
+ g = glob.MustCompile(glob.QuoteMeta("*.github.com"))
+ g.Match("*.github.com") // true
+
+ // create new glob with set of delimiters as ["."]
+ g = glob.MustCompile("api.*.com", '.')
+ g.Match("api.github.com") // true
+ g.Match("api.gi.hub.com") // false
+
+ // create new glob with set of delimiters as ["."]
+ // but now with super wildcard
+ g = glob.MustCompile("api.**.com", '.')
+ g.Match("api.github.com") // true
+ g.Match("api.gi.hub.com") // true
+
+ // create glob with single symbol wildcard
+ g = glob.MustCompile("?at")
+ g.Match("cat") // true
+ g.Match("fat") // true
+ g.Match("at") // false
+
+ // create glob with single symbol wildcard and delimiters ['f']
+ g = glob.MustCompile("?at", 'f')
+ g.Match("cat") // true
+ g.Match("fat") // false
+ g.Match("at") // false
+
+ // create glob with character-list matchers
+ g = glob.MustCompile("[abc]at")
+ g.Match("cat") // true
+ g.Match("bat") // true
+ g.Match("fat") // false
+ g.Match("at") // false
+
+ // create glob with character-list matchers
+ g = glob.MustCompile("[!abc]at")
+ g.Match("cat") // false
+ g.Match("bat") // false
+ g.Match("fat") // true
+ g.Match("at") // false
+
+ // create glob with character-range matchers
+ g = glob.MustCompile("[a-c]at")
+ g.Match("cat") // true
+ g.Match("bat") // true
+ g.Match("fat") // false
+ g.Match("at") // false
+
+ // create glob with character-range matchers
+ g = glob.MustCompile("[!a-c]at")
+ g.Match("cat") // false
+ g.Match("bat") // false
+ g.Match("fat") // true
+ g.Match("at") // false
+
+ // create glob with pattern-alternatives list
+ g = glob.MustCompile("{cat,bat,[fr]at}")
+ g.Match("cat") // true
+ g.Match("bat") // true
+ g.Match("fat") // true
+ g.Match("rat") // true
+ g.Match("at") // false
+ g.Match("zat") // false
+}
+
+```
+
+## Performance
+
+This library is created for compile-once patterns. This means, that compilation could take time, but
+strings matching is done faster, than in case when always parsing template.
+
+If you will not use compiled `glob.Glob` object, and do `g := glob.MustCompile(pattern); g.Match(...)` every time, then your code will be much more slower.
+
+Run `go test -bench=.` from source root to see the benchmarks:
+
+Pattern | Fixture | Match | Speed (ns/op)
+--------|---------|-------|--------------
+`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my cat has very bright eyes` | `true` | 432
+`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my dog has very bright eyes` | `false` | 199
+`https://*.google.*` | `https://account.google.com` | `true` | 96
+`https://*.google.*` | `https://google.com` | `false` | 66
+`{https://*.google.*,*yandex.*,*yahoo.*,*mail.ru}` | `http://yahoo.com` | `true` | 163
+`{https://*.google.*,*yandex.*,*yahoo.*,*mail.ru}` | `http://google.com` | `false` | 197
+`{https://*gobwas.com,http://exclude.gobwas.com}` | `https://safe.gobwas.com` | `true` | 22
+`{https://*gobwas.com,http://exclude.gobwas.com}` | `http://safe.gobwas.com` | `false` | 24
+`abc*` | `abcdef` | `true` | 8.15
+`abc*` | `af` | `false` | 5.68
+`*def` | `abcdef` | `true` | 8.84
+`*def` | `af` | `false` | 5.74
+`ab*ef` | `abcdef` | `true` | 15.2
+`ab*ef` | `af` | `false` | 10.4
+
+The same things with `regexp` package:
+
+Pattern | Fixture | Match | Speed (ns/op)
+--------|---------|-------|--------------
+`^[a-z][^a-x].*cat.*[h][^b].*eyes.*$` | `my cat has very bright eyes` | `true` | 2553
+`^[a-z][^a-x].*cat.*[h][^b].*eyes.*$` | `my dog has very bright eyes` | `false` | 1383
+`^https:\/\/.*\.google\..*$` | `https://account.google.com` | `true` | 1205
+`^https:\/\/.*\.google\..*$` | `https://google.com` | `false` | 767
+`^(https:\/\/.*\.google\..*|.*yandex\..*|.*yahoo\..*|.*mail\.ru)$` | `http://yahoo.com` | `true` | 1435
+`^(https:\/\/.*\.google\..*|.*yandex\..*|.*yahoo\..*|.*mail\.ru)$` | `http://google.com` | `false` | 1674
+`^(https:\/\/.*gobwas\.com|http://exclude.gobwas.com)$` | `https://safe.gobwas.com` | `true` | 1039
+`^(https:\/\/.*gobwas\.com|http://exclude.gobwas.com)$` | `http://safe.gobwas.com` | `false` | 272
+`^abc.*$` | `abcdef` | `true` | 237
+`^abc.*$` | `af` | `false` | 100
+`^.*def$` | `abcdef` | `true` | 464
+`^.*def$` | `af` | `false` | 265
+`^ab.*ef$` | `abcdef` | `true` | 375
+`^ab.*ef$` | `af` | `false` | 145

+## Syntax
+
+Syntax is inspired by [standard wildcards](http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm),
+except that `**` is aka super-asterisk, that do not sensitive for separators. \ No newline at end of file
