 Detailed Instructions for building with macosx/GNUmakefile

-- Unpack the tcl source release archive.
-
-- The following instructions assume the tcl source tree is named "tcl${ver}",
-where ${ver} is a shell variable containing the tcl version number (for example
-'8.4.12').
-Setup the shell variable as follows:
-	set ver="8.4.12" ;: if your shell is csh
-	ver="8.4.12"	 ;: if your shell is sh
-The source tree will be named this way only if you are building from a release
-archive, if you are building from CVS, the version numbers will be missing; so
-set ${ver} to the empty string instead:
-	set ver=""	 ;: if your shell is csh
