And those programmes are user experience disasters. I hate them with a
passion.

I will always, given the opportunity, use the 
many-ifs-and-set-an-error-flag approach. Who has not tried to invokes 
some minorly complicated programme in several goes, fixing one thing 
only to trip over the next. A PITA.

My most notable recent example was an environment setup script for 
something; it had a step where it probes for a dozne or so required 
peices of software, and complained and quit at the first missing one.

When that logic is buried deep in a subsidiary script, the user is 
massively annoyed. I submitted a small patch to probe for _all_ the 
software, complain about each missing comonepnt, and _then_ quit. Really 
easy and avoids much anger in the end user.
