Here is a roadmap to the R4 sources:

        README           this file
        RELNOTES.PS      R4 release notes in PostScript
        RELNOTES.txt     R4 release notes in plain text
        RELNOTES.lpt     R4 release notes in lpt format
        R4notice         R4 announcement (also where to get X)
        ERRATA           helpful hints
	fixes/           official patches to core software      (recommended)
	../../contrib/R4fixes/		patches to user-contributed software
        tape-1/          core software for X Window System      (required)
        tape-2/          contrib clients and core doc           (recommended)
        tape-3/          contrib libraries and other toolkits   (optional)
        tape-4/          contrib Andrew, games, etc.            (optional)

The split pieces are all 512k (524288 bytes) long (except for the last one in
each directory) and must be transfered in image mode (use the ftp "binary"
and "mget" commands).  If you are doing an "mget" you'll probably want to 
restart ftp with the "-i" option to prevent it from asking you about every
file.

Each directory contains a CHECKSUMS file containing both BSD- and SYSV-style
checksums (generated with the "sum" command) and a FILES.Z file containing a
compressed listing of the files stored in that directory.

To extract the sources into another directory (e.g. /usr/local/src/R4/), make
sure you have LOTS of disk space and type the following in each of the
directories that you have copied over:

	%  cat *.?? | uncompress | (cd /usr/local/src/R4/; tar xvf -)

While you are waiting for it to finish, get lunch and read the release notes!
