description="
An interactive process viewer for Unix systems.

Comparison between htop and classic top
* In htop you can scroll the list vertically and horizontally
  to see all processes and full command lines.
* In top you are subject to a delay for each unassigned
  key you press (especially annoying when multi-key escape
  sequences are triggered by accident).
* htop starts faster (top seems to collect data for a while
  before displaying anything).
* In htop you don't need to type the process number to
  kill a process, in top you do.
* In htop you don't need to type the process number or
  the priority value to renice a process, in top you do.
* In htop you can kill multiple processes at once.
* top is older, hence, more tested.
