Since they emulate direct user interaction, shell scripts are often the straightforward choice for task automation.
## Basic Utilities
One of my biggest pet-peeves with scripting is when every line of a *(insert-language-here)* program is escaped to shell.
This kind of program, which doesn't use language features, should be a shell script.
While there are definitely unavoidable limitations to shell scripting, we can minimize a variety of problems with a modern shell and shared utilities library.
Loaded by `common.zsh`, the [`utils/` library](./utils) provides:
- common function wrappers to unify flags and context
- lazy dependency and environment variable validation
