In other words, if 'target' exists and is newer than every file in 'sources', return false; otherwise return true. '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we silently drop any missing source files; if it is "newer", any missing source files make us assume that 'target' is out-of-date (this is handy in "dry-run" mode: it'll make you pretend to carry out commands that wouldn't work because inputs are missing, but that doesn't matter because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). i i ( u ST_MTIMEu erroru ignoreu newerN( u osu pathu existsu statu ST_MTIME( u sourcesu targetu missingu ST_MTIMEu target_mtimeu sourceu source_mtime( ( u7 /opt/alt/python33/lib64/python3.3/distutils/dep_util.pyu newer_group6 s u newer_group( u __doc__u osu distutils.errorsu DistutilsFileErroru neweru newer_pairwiseu newer_group( ( ( u7 /opt/alt/python33/lib64/python3.3/distutils/dep_util.pyu <module> s
