parentdebian: Remove a now useless substvar. (diff)
Moved testlibraw.c from src to tools directory.
Added sendiso and dumpiso programs in tools directory. Added man pages for sendiso and dumpiso in doc directory. git-svn-id: svn://svn.linux1394.org/libraw1394/trunk@66 53a565d1-3bb7-0310-b661-cf11e63c67ab
