+
+    imag - the personal information management suite for the commandline
+
+    imag is a PIM suite for the commandline. It consists of several commands,
+    called "modules". Each module implements one PIM aspect and all of these
+    modules can be used independently.
+
+    Available commands:
+    $(for cmd in $cmds; do
+        echo -e "\t$(echo $cmd | sed -r 's,(.*)/imag-(.*),\2,')";
+    done)
+
+    Call a command with "imag <command> <args>"
+    Each command can be called with "--help" to get the respective helptext.
+

+    follow the development of imag or maybe even contribute to imag.
