parentFix Multi-Block Stream encoder's EOPM usage. (diff)
downloadxz-cf49f42a6bd40143f54a6b10d6e605599e958c0b.tar.xz
Added lzma_easy_* functions. These should make using
liblzma as easy as using zlib, because the easy API don't require developers to know any fancy LZMA options. Note that Multi-Block Stream encoding is currently broken. The easy API should be OK, the bug(s) are elsewhere.
