LLgen uses Prime Mover as its build tool. To build, do:

./pm install

make install

This will compile LLgen and install it into /usr/local (which you must be able

./pm -DPREFIX="/home/dg/" install

make install PREFIX=/home/dg

(If you do change the prefix, you must supply it whenever you invoke pm,

whether you're installing or just building. And there must be a trailing / in

the path you give it.)

Invoking ./pm by itself will compile it but not install it; look in the bin

directory for an image of the installation directory.

(If you do change the prefix, you must do a `make clean` first, or else the

installed binary will look for its libraries in the wrong place.)
