      Welcome! This program will quickly install TERM on your system. This
      install procedure consists of the following steps:

	      1.  Move the distribution files to the proper location
	      2.  Serialize your copy of TERM

      You may abort this install program at any time by pressing your
      interrupt key (typically <Del> or ^C).

      Press <Enter> to continue with the install.
