- * xz_pipe_decomp.c
- * A simple example of pipe-only xz decompressor implementation.
- * version: 2012-06-14 - by Daniel Mealha Cabrita
- * Not copyrighted -- provided to the public domain.
- *
- * Compiling:
- * Link with liblzma. GCC example:
- * $ gcc -llzma xz_pipe_decomp.c -o xz_pipe_decomp
- *
- * Usage example:
- * $ cat some_file.xz | ./xz_pipe_decomp > some_file
