- * Uses some ideas from xosview and top
- * Some comments paraphrased from the SUN man pages
- * Version 0.1 initial release (Dec 1999)
- * Version 0.2 added support for multiprocessor machines (Jan 2000)
- * Version 0.3 some reliability enhancements and compile time fixes (Feb 2000)
- * Version 0.4 portability issue and raw cpu value support (Jun 2000)
- * Version 0.5 64-bit Solaris support and new data gathering routine (Aug 2000)
- * Version 0.6 Memory savings, overroll precautions and lint checks (Aug 2000)
- * Version 0.7 More raw counters and some cosmetic changes (Jan 2001)
