The variable ALDORROOT should point to the directory where Aldor is installed. It is assumed that this variable is set in the environment.
We assume that the compiler is in the bin subdirectory and the libraries are in the lib subdirectory.
The variable PROJECTROOT should be set when this file is included. It is usually set at the top of each Makefile.nw of ALLPROSE. The TOOLS directory is used for helper applications of ALLPROSE like Perl scripts.
