🐛 Update: Added support for the 'find' command in settings.local.json. Enhanced logging for various modules, including initialization and performance metrics. Improved SQLite database optimization and ensured better tracking of user interactions and system processes. 📚

+# example
+
+``` js
+var safe = require('safe-regex');
+var regex = process.argv.slice(2).join(' ');
+console.log(safe(regex));
+```
+
+```
+$ node safe.js '(x+x+)+y'
+false
+$ node safe.js '(beep|boop)*'
+true
+$ node safe.js '(a+){10}'
+false
+$ node safe.js '\blocation\s*:[^:\n]+\b(Oakland|San Francisco)\b'
+true
+```
+
+# methods
+
+``` js
+var safe = require('safe-regex')
+```
+
+## var ok = safe(re, opts={})
+
+Return a boolean `ok` whether or not the regex `re` is safe and not possibly
+catastrophic.
+
+`re` can be a `RegExp` object or just a string.
+
+If the `re` is a string and is an invalid regex, returns `false`.
+
+* `opts.limit` - maximum number of allowed repetitions in the entire regex.
+Default: `25`.
