5.0.0

• Now allows passing a directory as the input (all files in the directory will be processed)
• The CLI is now silent by default; added --verbose flag for if you want noisy logs
• Doesn't exit watch mode when there's an error in the plugin chain
• Removed non-obvious shorthand arguments (-x, -p, -s, -t, -e, -b, & -c). Also removed -v as an alias for --version.
• Prevent stupid option combinations like --dir & -o, and --watch & --replace
• Doesn't allow --watch when writing to STDOUT
