This package provides access to platform dependent file locking APIs:
*
Open file descriptor locking> on Linux ("Lukko.OFD") * BSD-style 'flock(2)'
locks on UNIX platforms ("Lukko.FLock") * Windows locking via
LockFileEx> ("Lukko.Windows") * No-op locking, which throws exceptions
("Lukko.NoOp") * "Lukko" module exports the best option for the target platform
with uniform API.
There are alternative file locking packages:
* "GHC.IO.Handle.Lock" in 'base >= 4.10' is good enough for most use cases.
However, uses only 'Handle's so these locks cannot be used for intra-process
locking. (You should use e.g. 'MVar' in addition).

locking.
