The main difference is that it is built to allow defining custom random number generating
functions via C function pointers (see
include/callback.h). When using the library,
these should be defined before calling any of the random functions.
Rmath-julia requires GNU Make (https://www.gnu.org/software/make). Just run
make to compile the library.
To update to the latest version of R, bump the
RVERSION file, and run
make update. Some additional manual changes to the headers may be necessary: these should go
include/Rconfig.h (this would typically be generated by autotools, but we try to
simplify the build process).
