 Fast resizable golang semaphore based on CAS
 
 * allows weighted acquire/release;
 * supports cancellation via context;
 * allows change semaphore limit after creation;
-* faster than channels based semaphores.
+* faster than channel based semaphores.
 
 ### Usage
 Initiate
 ```go
 import "github.com/marusama/semaphore"
 ...
-sem := semaphore.New(5) // new semaphore with limit=5
+sem := semaphore.New(5) // new semaphore with limit = 5
 ```
 Acquire
 ```go

semaphore_test.go
