Tomcar 4.0.1 Installation

[Stan Levine]

In the instructions for "Building The Tomcat 4.0 Servlet/JSP Container", several steps 
say to download into a convenient location. I'm not sure what "convenient location" 
means. Where should these downloads ultimately reside? I refer to  step (3) 
xerces-x_y_z,step (4) jakarta-tomcat-4.0. and (5)jakarta-serv;etapi-4.  Thanks, Stan
