+# psr-log-aware-trait
+
+Trait to allow support of different psr/log versions. 
+
+By including this PsrLogAwareTrait, you can allow composer to resolve your PsrLogger version for you. 
+
+## Use
+
+Require the trait. 
+
+        composer require chromatic/psr-log-aware-trait
+
+
+In your code, you no longer have to set a $logger property on your classes, since that comes with the trait, and you do not need to implement the `function setLogger()` method, since that also comes along with the trait. 
+
+```php
+use PsrLogAwareTrait;
+```
+        
+Will allow you to call `setLogger()` in your classes and fulfil the requirements of the PsrLoggerAwareInterface implementation.
