 It is basically a `ls` or a simple `find` specialized on `.nit` source files.
 
+By default `nitls` works with the current directory (`.`).
+
+Each file can then be:
+
+* A Nit module (file).
+  In this case, only this single module is considered
+* A Nit group (directory).
+  In this case, all the modules of the groups (and recursively the sub-groups) are considered
+* A normal directory.
+  In this case, all its entries are analysed.
+  Files that are Nit modules and directories that are Nit groups are considered.
+  Other files and directories are ignored.

 # EXAMPLES
 
-Show the tree of modules from the current directory and subdirectories.
