$ rm -f `find . -name \*\.pump`

# Move all the source files to the current directory
$ mv src/* .
$ rmdir src

# Move extra headers into the already-existing internal headers dir
$ mv *.h include/gtest/internal/

# Update paths to the included files
$ perl -pi -e 's|^#include "src/|#include "gtest/internal/|' *.cc

$ rm -f gtest-all.cc gtest_main.cc

$ mv COPYING LICENSE.TXT
