+### Simple

 * Color in bold red every occurrence of the word _color_ in colout sources:
   `cat colout.py | colout color red bold`
 
 * Color in bold violet home directories in _/etc/passwd_:
   `colout '/home/[a-z]+' 135 < /etc/passwd`
 
-* Use a different color for each line of the auth log
-  `grep user /var/log/auth.log | colout "^.*$" rainbow`
-
 * Color in yellow user/groups id, in bold green name and in bold red home directories in _/etc/passwd_:

+### Bash alias
+
+The following bash function color the output of any command with the
+cmake and g77 themes:
+
+    function cm()
+    {
+        set -o pipefail
+        $@ 2>&1  | colout -t cmake | colout -t g++
+    }
+
+You then can use the `cm` alias as a prefix to your build command,
+for example: `cm make test`
