# This build file prints out a list of open file descriptors in
# Ninja subprocesses, to help verify we don't accidentally leak
# any.

# Because one fd leak was in the code managing multiple subprocesses,
# this test brings up multiple subprocesses and then dumps the fd
# table of the last one.

# Use like: ./ninja -f misc/inherited-fds.ninja
