source: trunk/mindi-busybox/debianutils/pipe_progress.c @ 863

Last change on this file since 863 was 821, checked in by bruno, 13 years ago

Addition of busybox 1.2.1 as a mindi-busybox new package
This should avoid delivering binary files in mindi not built there (Fedora and Debian are quite serious about that)
