SOURCE BUG Duration: 11s

Subject

New applets, ftpget and ftpput

SOURCE BUG

This commit was genuinely broken at the time (not related to our build system): sysdeps/linux/Config.in "fileutils/Config.in" dosyasini kaynak gosteriyor ama bu dosya repoda hic var olmadi (2002-12-05 - 2003-02-15 arasi orijinal yazar hatasi, 3238ea167 ile duzeltildi)

→ Bu hatanin tam hikayesini ve duzeltme diffini gor
