+Description: Modern replacement for ls
+ eza is a modern replacement for ls.  It uses colours for information by
+ default, helping you distinguish between many types of files, such as whether
+ you are the owner, or in the owning group.
+ .
+ It also has extra features not present in the original ls, such as viewing the
+ Git status for a directory, or recursing into directories with a tree view.
