From the developer:
SIMBL (SIMple Bundle Loader) - pronounced like "symbol" or "cymbal" - enables hacks and plugins. For instance, SIMBL enables PithHelmet to enhance Safari.
SIMBL plugins are nothing more than standard Cocoa bundles created by XCode, with the addition of one key in the Info.plist.
