+GNU Bison 1.28
+
+For the import of Bison several directories and files were removed.
+The stripped down version was created using FreeBSD-Xlist during extraction:
+
+	tar -X FREEBSD-Xlist -xvzf bison-1.28.tar.gz
+
+Bison 1.28 changes the directory structure from previous releases.
+In addition, v1.25 seems to have had a spammed ChangeLog.  Bison v1.26 fixed
+this.  Thus the reason 1.28's ChangeLog's are hard to corelate with v1.25's.
+
+To reduce the size of import, and to make it so the changes from 1.25 and
+1.28 are easy to determine, the 1.28 directory structure is munged before
+import:
+
+	cd bison-1.28
+	mv src/ChangeLog ChangeLog.src
+	mv src/bison.s1 bison.simple
+	mv src/* .
+	rmdir src
+	mv doc/ChangeLog ChangeLog.doc
+	mv -i doc/* .			# answer "no" to all questions
+	rm -rf doc
+
+
+Imported by:
+
+	cvs import -ko -m 'Virgin import of GNU Bison 1.28' \
+		src/contrib/bison FSF v1_28
+
+
+To make local changes to Bison, simply patch and commit to the main
+branch (aka HEAD).  Never make local changes on the vendor (FSF) branch.
+
+All local changes should be submitted to the FSF for inclusion in the 
+next vendor release.
