vhdl mode

I am a beginner of Xemacs. My operating system is Microsoft XP. I want to use some texts in vhdl. I have downloaded the files: * vhdl-mode.el * vhdl-mode.texi * package-info.in * Makefile * ChangeLog * .cvsignore from the site http://cvs.xemacs.org/viewcvs.cgi/XEmacs/packages/xemacs-packages/vhdl / I have copied the files in the directory XEmacs\xemacs-packages\lisp\vhdl-modes, but it doesn't work. I have read the manual xemacs-a4.pdf of Xemacs and I have not found anything of the configuration of the Major Mode. What do I have to do? Thanks Marco
