File README added (mode: 100644) (index 0000000..a8a9184)
1 This is a code extraction of libuuid and uuidgen from util-linux.
2
3 The main purpose is to get a symbol collision secure static linking of
4 libuuid.a.
5
6 ... and no autotools, libtool, cmake, meson, scons, ninja, perl, python... in
7 the SDK.... YEAY!
8
9 The "configuration" is set is stone, but this is only the first commit.
