Hello, after a walk through the tools/src directory and sometime to search the whole internet, I found these files are from third party which have no copyright disclaimer:
DeKDic.exe, KSDrip.exe: binary without source, should be of course removed, upstream of stardict said they're useful and refused to remove. dictgen.php: cannot found the author. extractKangXi.py, makevietdict.py: the author is call wesnoth on ustc bbs [1] around 2007, without contact information now. sd2foldoc.cpp, libsd2foldoc.cpp, libsd2foldoc.h: the author is dazhiqian, the code is still downloadable via google code page [2], and the project page said it's New BSD License, so we are safe to assume it's 3-clause BSD. And there are several simple scripts which have no disclaimers, I don't think we should bother dealing with them, because they are too simple, both by lines(less than 10 lines) or functions (print some lines and replace some vars). for example: KangXiZiDian-djvu2tiff.py and stmerge.py. So, I'll repack the upstream source, remove *.exe, dictgen.php, extractKangXi.py, makevietdict.py, add disclaimer to sd2foldoc, and all should be OK. BTW, Po2Tab.zip is all clear, the copyright notice is there, the author is clear, it's a piece of tool to convert gettext .po file into stardict tab file, it's java source so been packed into an archive, for whoever interesting to open it :) [1] http://webcache.googleusercontent.com/search?q=cache:UThieVUFQu0J:bbs.bo69.cn/cgi/bbscon%3Fbn%3DHanyu%26fn%3DM46C12B07%26num%3D111+&cd=2 [2] https://code.google.com/archive/p/dazhiqian/, download source, found at /trunk/C/dictd-dabase -- Emfox Zhou GnuPG Public Key: 0x10000DEB
