Make is a GNU tool which allows users to build and install programs
without any significant knowledge of the build process. Details about
how the program should be built are included in the program's
Makefile. Pmake is a particular version (BSD 4.4) of make. Pmake
supports some additional syntax which is not in the standard make
program. Some Berkeley programs have Makefiles written for pmake.
Pmake should be installed on your system so that you will be able to
build programs which require using pmake instead of make.
