# Usage: create a file foo.c, make foo a symlink to this script
# When foo is executed, this script silently compiles foo.c into .make-and-exec-binaries/foo and execs that with the arguments provided.
# The compilation goes through make, so later invocations directly exec the binary with little delay.
# To customise the compilation, you can set a CFLAGS env var before running foo.
