autotools-idl is a patch for automake and some autoconf scripts that adds support for IDL and C++ ORBs. It provides full support for compiling IDL files to C++ stubs and skeletons. The autoconf scripts provide unified detection of different C++ ORBs.
The nsisPatchGen utility recursively compares two directory structures looking for changes to the files and subdirectories. It produces an NSIS include file containing functions that will perform a patch upgrade from the original structure to the new.
