Look in the Tcl distribution for the file called "porting.notes". This
will contain a collection of notes that various people have provided
about porting Tcl to various machines and operating systems. There is
also a file called "README" which should be read FIRST - before doing
anything else with the code (this should always be one`s first step with
any package). Further, there is a "changes" file which details what has
changed since the last release - be sure to read this to see what might
need to change in your programs.
