This is the lib directory for seadali, directory $OCEAN/lib/seadali.

The 'secret' feature of seadali......

This directory is not absolutely essential, it is just for fun.
However, with students this secret feature of seadali is very 
popular. 

Seadali might show a picture to you in the following case:

     - the environment variable SEADALI_NO_PICTURES was NOT set.
     - the current cpu load is smaller than 2.
     - the program 'xv' (a gif viewer) exists and is in the path, 
     - the file $OCEANPATH/lib/seadali/madonna_picture_list or 
       $OCEANPATH/lib/seadali/madonna_picture_list exists.
     - the selected picture from this file exists

If all of the above conditions are met, a picture will be displayed 
in the following cases:

     - with a certain random probability if you click 'madonna' or 'trout'.
     - always if you click 'place&route'
     - always if you click in the top text window.

In all other cases seadali will say nothing.

In the file 'madonna_picture_list' or 'trout_picture_list' of this 
directory you can specify a collection of pictures (including their
paths).
