Binaries for Windows 32-bit and 64-bit ugrep.exe and ugrep-indexer.exe are
included: building ugrep on Windows takes some serious effort to install and
compile PCRE2 and all of the compression libraries together with ugrep with the
proper configuration settings of C++ dev tools.  Visual Studio ugrep.exe build
instructions can be found in vs/ugrep/README.txt
