+THIS IS HERE ONLY TO SUPPORT SYSTEMTAP DEVELOPMENT.  IT IS NOT FOR GENERAL USE.
+
+Building systemtap requires a recent development version of elfutils,
+which provides libraries for making use of debugging information.
+
+This is unfinished work in active development.  This code is not intended
+for general consumption in its present form.  Development of these
+libraries is simultaneous with Systemtap development.  The Systemtap code
+will require new versions as things evolve; the systemtap.spec.in file in
+the systemtap source tree should always indicate the minimum version of
+elfutils libraries that will suffice.  We will make an effort to make a
+compatible version available here, that you can use for compiling Systemtap.
+
+Current elfutils can always be found in Fedora Core Development, AKA Rawhide.
+If you are interested in the elfutils code in general or for any purpose
+other than developing Systemtap, please see http://fedora.redhat.com/ about
+getting involved with Fedora Core Development directly.
+
+You can find the rawhide rpms updated daily on a variety of sites
+(see http://fedora.redhat.com/download/mirrors.html) under core/development.
+What's distributed in this directory is made trivially from those same sources.
+
+The vanilla elfutils code, in elfutils-VERSION.tar.gz and what the rawhide
+RPMs ordinarily build, can only be built using GCC 4 and a recent glibc.
+Fedora Core 4 is the only released system meeting the requirements.
+
+To rebuild the rawhide src.rpm on an older system, you can use:
+
+	rpmbuild --with compat --rebuild elfutils-VERSION-N.src.rpm
+
+The SRPMS/elfutils-VERSION-0.N.src.rpm provided here is exactly the same as
+the elfutils-VERSION-N.src.rpm from Rawhide except that it doesn't require
+that you specify --with compat to build on an older system.
+
+We have done this for you for a few architectures, and those RPMs are
+available here.  These were built on RHEL3, and so their requirements
+should not be too demanding.  We must remind you that this is unsupported,
+pre-beta development code.  Furthermore, these builds are completely
+unofficial, unsupported, unsigned, unlikely to have been tested,
+unequivocally not guaranteed not to ruin your whole day, and we really
+cannot recommend that anyone install them on their system.  Do so at your
+own risk.  All that said, here they is, and if you copy this file:
+
+	ftp://sources.redhat.com/pub/systemtap/elfutils/systemtap-elfutils.repo
+
+into your /etc/yum.repos.d/ directory, then you can get them with:
+
+	yum install elfutils-libelf-devel
+
+
+To compile elfutils from source by hand, simply use elfutils-VERSION.tar.gz
+and follow the usual procedure for GNU configure conventions.  The patch
+available here has to be applied before you can compile on an older system:
+
+	tar xzf elfutils-VERSION.tar.gz
+	patch -p1 -d elfutils-VERSION < elfutils-portability.patch
+	cd elfutils-VERSION
+	./configure && make && make check && make install
+
+(That of course installs things under /usr/local, unlike the RPMs.)
+
