## About Process Safe Logger

Process Safe Logger supports log rotations in multi-processes *safely*.

## Objective

Ruby's standard Logger class originally have had a problem that it's log rotation function does not work safely in multi process environment. This gem fixes the problem. 

The patch is already pull requested to the [github.com:ruby/ruby](https://github.com/ruby/ruby/pull/428) and will be released with ruby 2.1.0. 

## Installation

    gem install process_safe_logger

## Usage

```ruby
require 'process_safe_logger'
logger = ProcessSafeLogger.new('logfile.log', 3, 1024)
```

Option parameters are same with Ruby's Logger. See [docs.ruby-lang.org:Logger](http://docs.ruby-lang.org/en/2.0.0/Logger.html).
