# This script helps creating project files for abseil-cpp.  The argument is the path of a subdirectory of absl/.
# It produces three pairs of *.vcxproj, *.vcxproj.filters files: one for the subdirectory being operated upon,
# one for the benchmarks project and one for the tests project.  For the first pair, the generated XML may just
# be inserted at the right place in the project files, replacing whatever was there.  For the benchmarks and tests
# things are more complicate as the generated XML must be inserted at the right place.
# TODO(phl): The next time we do this dance, start by beefing up the script to generate the complete files for
# benchmarks and tests in one fell swoop.  That will save a lot of time and errors.
