/* Some platforms, notably macOS, ship a usable liblzma shared library but
|
|
do not ship any LZMA header files. The <lzma.h> and <lzma/{*}.h> header
|
|
files that come with the library contain the following statement:
|
|
|
|
*

|
* Author: Lasse Collin
|
|
*
|
|
* This file has been put into the public domain.
|
|
* You can do whatever you want with this file.
|
|
*
|
|
|
|
Accordingly the following declarations have been copied and distilled
|
|
from <lzma/base.h> and <lzma/container.h> (primarily) and are sufficient
|
|
to compile cram/cram_io.c in the absence of proper LZMA headers.
|
|
|
|
This file, lzma_stub.h, remains in the public domain. */
