+* Dependency tracking (if a file imported by other files changes, they get
+  compiled).
+* Growl notifications (a notification with summary shows up after each time
+  something is compiled).

 Usage
 -----
 
     $ npm install autoless -g
     $ autoless --help

+Pausing and resuming
+--------------------
+
+You can pause watching files by creating a .lessignore file in your
+source directory (the one with .less files). When the file is removed,
+watching is resumed.
+
+You can use that e.g. in Git's `pre-rebase` and `post-rewrite` hooks to
+avoid confusing Git when rebasing.
