-This directory contains MPW scripts and related files that are needed to
-build Cygnus GNU tools for MPW.  The scripts should be somewhere on the
-command path; our usual practice has been to have a separate directory
-for the scripts, and put the tools (byacc, flex, and sed at least) there
-also; then it's easier to drag the support bits around as a group, or to
-upgrade MPW versions.  The complete package of scripts and tool binaries
-is usually available as pub/mac/buildtools.cpt.hqx on ftp.cygnus.com.
-
-"tr-7to8-src" is actually the source to an MPW script that transforms
-sequences like "\Option-d" into the actual 8-bit chars that MPW needs.
-It's only the source because it can't itself include any 8-bit chars.
-It *can* be processed into a genuine "tr-7to8" by using itself:
-
-	tr-7to8 tr-7to8-src | sed -e 's/Src//' >new-tr-7to8
-
-Use this to verify:
-
-	compare tr-7to8 new-tr-7to8
-
-If you don't have a working tr-7to8, then you will have to manually
-replace all occurrences of "\Option-d" with real Option-d (which looks
-like a delta), then do similarly with all the other "\Option-..."
-strings, and then change "\SrcOption-d" into the string "\Option-d".
