Toggles error handling in the current config before the opposite command. Catch_errors stops program execution, if a failure occurs at any step.
Usage:

<some code in which errors should be ignored>
catch_errors
<some code in which errors are unacceptable>
ignore_errors
<some code in which errors should be ignored>

Exclusively for Uberhand

One of the best use cases for catch_errors is to stop execution when a download or decompression fails.

By default, error handling is disabled for backwards compatibility, so you don’t need to use ignore_errors in every script.
