# Zig provides its standard library in source form "/opt/zig-bin-{PV}/lib/",
# and all other Zig libraries are meant to be consumed in source form,
# because they can use compile-time mechanics (and it is easier for distributions to patch them)
# Here we use this feature for fixing programs that use standard library
# Note: Zig build system is also part of standard library, so we can fix it too
