liblzma-dev - 5.2.4-1+deb10u1 main

XZ is the successor to the Lempel-Ziv/Markov-chain Algorithm
compression format, which provides memory-hungry but powerful
compression (often better than bzip2) and fast, easy decompression.
.
The native format of liblzma is XZ; it also supports raw (headerless)
streams and the older LZMA format used by lzma. (For 7-Zip's related
format, use the p7zip package instead.) This package provides the
development library needed to build programs using liblzma.
