* This little piece of code is used to insert some code into LyX's
* Resources/lyx/configure script so that it will cause lyxrc.defaults to
* contain
*
* \path_prefix "<path to sh.exe>;<path to python.exe>;..."
*
* Compile the code with
*
* g++ -I/c/Program\ Files/NSIS/Contrib -Wall -shared \
* lyx_path_prefix.c -o lyx_path_prefix.dll
*
* Move resulting .dll to /c/Program\ Files/NSIS/Plugins
