22 * To achieve a small memory footprint, this version of 'ls' doesn't do any
23 * file sorting, and only has the most essential command line switches
24 * (i.e. the ones I couldn't live without :-) All features which involve
25 * linking in substantial chunks of libc can be disabled.
27 * Although I don't really want to add new features to this program to
28 * keep it small, I *am* interested to receive bug fixes and ways to make
32 * 1. ls -l of a directory doesn't give "total <blocks>" header
33 * 2. ls of a symlink to a directory doesn't list directory contents
34 * 3. hidden files can make column width too large
36 * NON-OPTIMAL BEHAVIOUR:
37 * 1. autowidth reads directories twice
38 * 2. if you do a short directory listing without filetype characters
39 * appended, there's no need to stat each one
41 * 1. requires lstat (BSD) - how do you do it without?
