+Changelog
+=========
+
+2.1.1
+-----
+
+ - Add Python 3.5 to travis
+
+2.1.0
+-----
+
+ - Same pid support, multiple calls to the same process won't
+ file when allow_samepid=True is set.
+
+2.0.1
+-----
+
+ - Bundle AUTHOR, CHANGELOG and LICENSE with source distribution
+
+2.0.0
+-----
+
+ - PidFile will now look at the environment variables it
+ needs just before acquiring the lock instead of at
+ instantiation time of the PidFile class.
+
+ - pid is now friendly with daemon context managers such
+ as python-daemon where the PidFile context manager is
+ passed as a parameter.
+
+ - The signal handler on SIGTERM is now only installed
+ automatically if there is no previous signal handler
+ installed.
+
+ - You can install a custom SIGTERM handler by specifying
+ a callable for 'register_term_signal_handler'.
+
+ - All in all we tried to make sure that with version 2.0.0
+ pid will play nice with other code and has sane defaults.
+
+ - Many thanks to nnathan who's efforts coding and testing
+ made this version possible.
+
+
+1.1.0
+-----
+
+ - Add pypy to classifiers and travis

+ PidFile class featuring:
+
+ - stale detection
+ - pidfile locking (fcntl)
+ - chmod (default is 0o644)
+ - chown

+
+ Context Manager
+ ---------------
+
+ PidFile can be used as a context manager::
+
+ from pid import PidFile

+ ---------
+
+ PidFile can also be used a a decorator::

+
+ @pidfile()
+ def main():
+ pass
+
+ if __name__ == "__main__":
+ main()
+
+
+ Exception Order
+ ---------------
+
+ In default mode PidFile will try to acquire a file lock before anything else.
+ This means that normally you get a PidFileAlreadyLockedError instead of the
+ PidFileAlreadyRunningError when running a program twice.
+
+ If you just want to know if a program is already running its easiest to catch
+ just PidFileError since it will capture all possible PidFile exceptions.
+
+ Behaviour
+ ---------
+
+ Changes in version 2.0.0 and going forward:
+
+ * pid is now friendly with daemon context managers such as
+ `python-daemon `_ where
+ the PidFile context manager is passed as a parameter. The
+ new corrected behaviour will ensure the process environment is
+ determinde at the time of acquiring/checking the lock. Prior
+ behaviour would determine the process environment when
+ instancing the class which may result in incorrect determination
+ of the PID in the case of a process forking after instancing
+ PidFile.
+
+ \
+
+ * Cleanup of pidfile on termination is done using `atexit` module.
+ The default SIGTERM handler doesn't cleanly exit and therefore
+ the atexit registered functions will not execute. A custom
+ handler which triggers the atexit registered functions for cleanup
+ will override the default SIGTERM handler. If a prior signal handler
+ has been configured, then it will not be overridden.
