shu2
shu2 (shell-utils version 2) is a general-purpose utility library for
scripts written with zsh 5.3+. It provides
settings and functions commonly needed when writing featureful command-line
tools. Much of the functionality it offers relates to error handling, output
verbosity control, and string manipulation; it also provides 'native' (i.e.,
fast and portable) alternatives to external utilities like date and sleep.
