 Introduction

+------------
 
 This is htop, an interactive process viewer.
 It requires ncurses. It is tested with Linux 2.6,

 Comparison between 'htop' and '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.

+When fetching the code from the development repository, you need
+to run the `./autogen.sh` script, which in turn requires autotools
+to be installed.
 
 See the manual page (man htop) or the on-line help ('F1' or 'h'
