Hi,

I switched yesterday to Fish as my main interactive 
shell (after using Zsh and Fizsh for a long time). To 
get acquainted to Fish I thought of converting my own 
shell script template to Fish - although I know that 
scripting is not Fish's main focus.

So here are my questions:

- does Fish have an equivalent for getopts? What's the 
recommended solution for parsing command options? 

- does Fish have an equivalent to the errexit option 
(stop execution on error)?

- does Fish have an equivalent to the nounset option 
(treat unset variables as error)?

- does Fish have an equivalent to the xtrace option 
(verbose script execution without full debugging)?

Thorsten
