+ * Uses the str_replace() method on a source string.
+ *
+ * @MigrateProcessPlugin(
+ *   id = "str_replace"
+ * )
+ *
+ * To do a simple hardcoded string replace use the following:
+ *
+ * @code
+ *   field_text:
+ *     plugin: str_replace
+ *     source: text
+ *     search: foo
+ *     replace: bar
+ * @endcode
+ *
+ * If the value of text is "vero eos et accusam et justo vero"
+ * in source, foo is "et" in search and bar is "that" in replace,
+ * field_text will be "vero eos that accusam that justo vero".
+ *
+ * Case insensitive searches can be achieved using the following:
+ * @code
+ *   field_text:
+ *     plugin: str_replace
+ *     case_insensitive: true
+ *     source: text
+ *     search: foo
+ *     replace: bar
+ * @endcode
+ *
+ * If the value of text is "VERO eos et accusam et justo vero"
+ * in source, foo is "vero" in search and bar is "that" in replace,
+ * field_text will be "that eos et accusam et justo that".
+ *
+ * Also regular expressions can be matched using:
+ * @code
+ *   field_text:
+ *     plugin: str_replace
+ *     regex: true
+ *     source: text
+ *     search: foo
+ *     replace: bar
+ * @endcode
+ *
+ * If the value of text is "vero eos et 123 accusam et justo 123 duo"
+ * in source, foo is "/[0-9]{3}/" in search and bar is "the" in replace,
+ * field_text will be "vero eos et the accusam et justo the duo".
+ *
+ * All the rules for
+ * @link http://php.net/manual/function.str-replace.php str_replace @endlink
+ * apply. This means that you can provide arrays as values.
