COPYRIGHT STATUS

The bulk of this code is copyright by members of or all of the R

Development Core Team.

See the file COPYING for the exact conditions under which you may

redistribute it.

	---------------------------------------------------

The public header files and import libraries are distributed under the

more permissive terms of the file COPYING.LIB.  This applies only to

the files

src/include/R.h

src/include/Rdefines.h

src/include/Rgraphics.h

src/include/Rinternals.h

src/include/Rmath.h

src/include/S.h

src/include/R_ext/*.h

src/gnuwin32/R.exp (a generated file in binary distributions only)

src/main/R.exp,  generated by tools/ldAIX4 whilst building R on AIX.

From the announcement of the change (2001-Feb-05)

    It came to our attention that some projects are interpreting GPL to

    mean that compiling against the header files or linking against a

    Windows import library brings the compiled code under the scope of

    GPL.  This would mean it would be impossible to distribute binary

    versions of non-GPL packages with compiled code which called entry

    points in the R executable or DLL, of which there are many on CRAN.

    We encourage packages to be distributed under Open Source conditions,

    but accept that this is not possible for some contributions.  Our

    intention is that export files and import libraries be `accessors'

    under clause 5 of the LGPL, so that in most cases no (additional)

    restrictions are imposed by compiling a package using the LGPL-ed

    components of R.

    To avoid any anomalies, the versions of the same files in R versions

    1.0.0 to 1.2.1 may also be used under LGPL or GPL.
