'missing' controls what we do when a source file is missing; the default ("error") is to blow up with an OSError from inside 'stat()'; if it is "ignore", we silently drop any missing source files; if it is "newer", any missing source files make us assume that 'target' is out-of-date (this is handy in "dry-run" mode: it'll make you pretend to carry out commands that wouldn't work because inputs are missing, but that doesn't matter because you're not actually going to run the commands). iiserrorsignoresnewerN( sosspathsexistsstargetsstatsST_MTIMEs target_mtimessourcesssourcesmissings source_mtime(ssourcesstargetsmissingsST_MTIMEs target_mtimessources source_mtimes:/usr/pkg/lib/python1.5/site-packages/distutils/dep_util.pys newer_group9s$        serrorcsSt||ƒo(|o|o |GHnt||ƒn|o|o |GHndS(s§Makes 'dst' from 'src' (both filenames) by calling 'func' with 'args', but only if it needs to: i.e. if 'dst' does not exist or 'src' is newer than 'dst'.
