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