Binary components
-----------------

The Windows binary distribution contains components that have been
compiled separately.  Most of these are from the Rtools distribution
at http://www.murdoch-sutherland.com/Rtools/;
http://www.murdoch-sutherland.com/Rtools/Rtools.txt lists the current
contents.

The build of Tcl/Tk contained in the binary installer was produced
by Adrian Waddell; see https://github.com/waddella/Tclbuild for 
instructions.  Sources are available via links on that page, or on
request from R-windows@r-project.org.

Rbitmap.dll is built against static libraries for libpng, jpeg and
libtiff: the Makefiles and configuration headers used are in the
src/gnuwin32/bitmap direcctory.  The exact sources used for these
libraries are available on request to R-windows@r-project.org (you
will need to specify which binary installer version).

A binay build may contain compiled sources from cairographics,
distributed under LGPL 2.1 (our choice) or MPL 1.1.  The binary
distribution used is that at https://www.rforge.net/Cairo/files/ .

A binary build may contain compiled components from ICU, whose license
can be viewed at
http://source.icu-project.org/repos/icu/icu/trunk/LICENSE: the
sources and binary libraries used are available at
http://www.stats.ox.ac.uk/pub/Rtools/ .
