The following is tried out with csh on Sun Solaris, on other systems details may differ.

0. Download/copy the directory femLego_dist from ~irina/femLego to a convenient location in your home directory.
   
1. If you do not have a .mapleinit file in your $HOME, copy femLego_dist/.mapleinit to your $HOME. Otherwise, add the contents of femLego_dist/.mapleinit to the existing $HOME/.mapleinit file.
   
2. Find out if a compiled version of the linear algebra library SLAP exists on the system. Otherwise, compile it according to instructions in femLego_dist/SLAP2.0, and put it in a convenient place.
   
3. Set the unix environment variable SLAP_LIB to the path for the directory where the SLAP library (i.e. libslap.a) is located, as determined above. This is preferably done by entering the line
   setenv SLAP_LIB <actual path>
in your $HOME/.cshrc

4. If necssary load Maple, typically by typing
   module add maple
   or something similar depending on the local system.
   
5. Go to femLego_dist/little_example. Open the file example.mws in Maple by typing
   xmaple example.mws &
   and execute it step by step, following instructions and comments there. This directory, as well as the other examples in femLego_dist, can be used as a template for new problems.
