+# 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
