# A Makefile for building semi-portable credentials-to-env binaries that
# should work on as many Linux distros as possible.  To do this, we build
# on an older Linux distro, and rely on the fact that we only link against
# common, stable shared libraries.

# We use this command to run our build inside a sandboxed Linux
# distribution which has a fairly old libc.  With luck, this should allow
# us to use the same binary on pretty much any modern Linux distribution,
# because it will only rely on an ancient build of libc.
