Cat with ASCII progress bar
This is a small shell script intended to be used in portable Unix install scripts for showing progress bars.

This is pure Bourne shell code. For sh, ash, ksh, zsh, bash, …
The script is mainly indented to be used in portable install scripts, where you can use the body of the script.
