# Overlay that builds static packages.

# Not all packages will build but support is done on a
# best effort basic.
#
# Note on Darwin/macOS: Apple does not provide a static libc
# so any attempts at static binaries are going to be very
# unsupported.
#
# Basic things like pkgsStatic.hello should work out of the box. More
# complicated things will need to be fixed with overrides.
