Font maintenance tool.
Smasher is a multipurpose font utility that enables creative professionals to extract optimal performance from their design applications. Smasher streamlines font suitcases and cleans font caches to eliminate a variety of common font problems and improve the performance of Mac OS X systems.
Smasher enables users to view all fonts in a suitcase - including legacy Mac OS 9 suitcases that may contain numerous fonts from a multitude of families and foundries - and smash the suitcases into their smallest components. To smash a suitcase, users simply select it and click the Smash button, or drag suitcases or fonts to the Desktop or a folder. Smasher automatically creates new, more efficient and manageable suitcases.
