ls - CS631 midterm

This small project implements a simplified version of the NetBSD `ls` utility. 

Build
-----
Run make in the project directory to build the program:

	make

This will produce an executable (named `ls`) according to the provided Makefile.

Usage
-----
Basic usage (example):

	./ls [options] [path]

Repository layout
-------------------------
- `ls.c`       - main program entry and command-line handling
- `ls.h`       - public declarations for the `ls` program
- `cmp.c/h`    - comparison routines (sorting, ordering)
- `print.c/h`  - printing/formatting of file entries
- `utils.c/h`  - utility helpers used across the project
- `flags.h`    - flag and option definitions
- `Makefile`   - build rules
- `checklist`  - assignment checklist (notes)
- `LOG`        - logs or run output saved by the author

Notes
-----
- There are many places in the code where checking combinations of flags 
is required; this led to a large number of nested conditionals and loops. 
As a result some parts of the implementation are messy and harder to follow. 
If there are suggestions for a cleaner approach, I'd appreciate the guidance.
