I have added some documentation to the README, INSTALL and NEWS files.

2009-04-29  Mark Wielaard  <mjw at redhat.com>

    * README: Document systemtap support.
    * INSTALL: Document build requirements for systemtap support.
    * NEWS: Mention systemtap support.

And updated the wiki http://icedtea.classpath.org/wiki/BuildRequirements
to document the new --enable-systemtap and --with-abs-install-dir
options plus build requirements when used.

Cheers,

Mark
