+at-ease
+=======
+
+at-ease is a PHP library that provides a safe alternative to PHP's
+[@ error control operator][].
+
+`@` is broken when `E_STRICT` is enabled and it causes an unlogged,
+unexplained error if there is a fatal, which is hard to support. The proper
+method of handling errors is to actually handle the errors. For example, if
+you are thinking of using an error suppression operator to suppress an invalid
+array index warning, you should instead perform an `isset()` check on the
+array index before trying to access it. When possible, always prevent PHP
+errors rather than catching and handling them afterward. It makes the code
+more understandable and avoids dealing with slow error suppression methods.
+
+However, there are some cases where warnings are inevitable, even if you check
+beforehand, like when accessing files. You can check that the file exists by
+using `file_exists()` and `is_readable()`, but the file could have been
+deleted by the time you go to read it. In that case, you can use this library
+to suppress the warnings and prevent PHP from being noisy.
+
+
+Usage
+-----
+
+    // Suppress warnings in a block of code:
+    \MediaWiki\suppressWarnings();
+    $content = file_get_contents( 'foobar.txt' );
+    \MediaWiki\restoreWarnings();
+
+
+    // ..or in a callback function:
+    \MediaWiki\quietCall( 'file_get_contents', 'foobar.txt' );
+
+
+Running tests
+-------------
+
+    composer install --prefer-dist
+    composer test
+
+
+History
+-------
+
+This library was first introduced in [MediaWiki 1.3][] ([r4261][]). It was
+split out of the MediaWiki codebase and published as an independent library
+during the [MediaWiki 1.26][] development cycle.
