+Symfony Deprecation Contracts
+=============================
+
+A generic function and convention to trigger deprecation notices.
+
+This package provides a single global function named `trigger_deprecation()` that triggers silenced deprecation notices.
+
+By using a custom PHP error handler such as the one provided by the Symfony ErrorHandler component,
+the triggered deprecations can be caught and logged for later discovery, both on dev and prod environments.
+
+The function requires at least 3 arguments:
+ - the name of the Composer package that is triggering the deprecation
+ - the version of the package that introduced the deprecation
+ - the message of the deprecation
+ - more arguments can be provided: they will be inserted in the message using `printf()` formatting
+
+Example:
+```php
+trigger_deprecation('symfony/blockchain', '8.9', 'Using "%s" is deprecated, use "%s" instead.', 'bitcoin', 'fabcoin');
+```
+
+This will generate the following message:
+`Since symfony/blockchain 8.9: Using "bitcoin" is deprecated, use "fabcoin" instead.`
+
+While not necessarily recommended, the deprecation notices can be completely ignored by declaring an empty
+`function trigger_deprecation() {}` in your application.
