Examples
Simple Usage:

Complex Usage with Nested Arguments:
long_arg --user-info name=Jane,age=25 --address street=Main St.,city=Springfield,state=CA
Common Issues
Error: Invalid Argument Format
- Ensure the argument string follows the correct syntax, with parameters separated by commas and nested arguments enclosed in parentheses.
Error: Argument Key Not Recognized
- Check the spelling and case of argument keys. Undefined keys will not be parsed.
Integration
With Grep: Filter specific parsed argument values from the output.
long_arg ... | grep -- --city
With Bash Scripting: Utilize parsed arguments in bash scripts for automated tasks.
name=$(long_arg ... --name)
echo "Hello, $name!"
