+   Obviously it is, because rgeos neither suggests, links to, imports or 
+   depends on the R gpclib package, nor does it load or attach that package.
+ .
+   The functions in R/gpc_geos.R convert sp objects to R gpclib classes, 
+   defined in R/Rgpc_funcs.R. The examples in man/gpc-new-generics.Rd 
+   expressly show how to use GEOS compiled code instead of gpclib compiled 
+   code to yield the same results. That is, when rgeos was first published in 
+   2011, one of its intentions was to show that nobody needed to use the 
+   R gpclib package with its awkward license, but that the code in 
+   R/Rgpc_funcs.R provided a drop-in replacement - load rgeos instead of 
+   gpclib and get the same output but without the gpclib license issue. The 
+   code copied from gpclib/R/Rgpc.R to rgeos/R is:
+ .
+   ## Copyright (C) 2003-2010 Roger D. Peng <rpeng at jhsph.edu>
+ .
+   Our understanding of the R gpclib LICENSE is that it only refers to the 
+   code written by Alan Murta and "taken" by this former employer - that is 
+   the files src/gpc.*. This is evidenced by the verbatim text of the package 
+   LICENSE file: Free for non-commercial use; commercial use prohibited (see 
+   the files `gpc.c' and `gpc.h' for details). Obviously C and R code written 
+   by the maintainer or contributed by others is not covered by this 
+   restriction.
+ .
+ .
+ Summarising the content of the last paragraph which is not worth quoting:
+ .
+ The purposes of rgeos is to provide a substitute for gpclib,  The LICENSE
+ file of the R gpclib package should have been drafted to state that only
+ src/gpc.* are covered by the conditions stated therein.
