FAQ

1. Which license is toprump released under?
   - The same as OpenBSD.
2. Has any toprump code made it in to the OpenBSD source tree?
   - Some bug fixes/code tidys/features that are in toprump have been applied to OpenBSD. See here.... Look for cvs commits that have Mark Lumsden in the cvs comments or lum@ as the Author.
3. Why bother having graphing functionality in top? Lots of other utilities can display the same info.
   - I'm not familiar with any utility that can display load average/cpu utilisation in graph format without X being installed. Let me know if there is. However, I wanted to add it anyway.
4. How does toprump calculate activity of the CPU used in the graph?
   - toprump uses the inverse of the idle figure on the 'CPU states' line to calculate processor usage.
5. What is the difference between the graph characters: '.', 'x', 'X'?
   - Please read the man page.
6. Where's the change log?
   - In the gzipped tarball.
7. Aren't these modifications just extra knobs?.
   - Arguably some are.
8. Top rump? Why not top side?
   - The opposite to top is bottom, not side.
