+/**
+ * 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.
