+A python package that provides useful locks.
+
+It includes the following.
+
+- Locking decorator
+
+    Helpful locked decorator (that acquires instance objects lock(s) and
+    acquires on method entry and releases on method exit).
+
+- Reader-writer locks
+
+    Multiple readers (at the same time).
+    Single writers (blocking any readers).
+    Helpful read_locked and write_locked decorators.
+
+- Inter-process locks
+
+    Single writer using file based locking (these automatically release on
+    process exit, even if __release__ or __exit__ is never called).
+    Helpful interprocess_locked decorator.
+
+- Generic helpers
+
+    A try_lock helper context manager that will attempt to acquire a given
+    lock and provide back whether the attempt passed or failed (if it passes, then
+    further code in the context manager will be ran with the lock acquired).
