  Description     : 7-Zip file archiver

7-Zip is a file archiver with a high compression ratio.

The main features of 7-Zip

 * High compression ratio in 7z format with LZMA and LZMA2 compression
 * Supported formats:
     * Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
     * Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT,
       HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM,
       SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.
 * For ZIP and GZIP formats, 7-Zip provides a compression ratio that is
   2-10 % better than the ratio provided by PKZip and WinZip
 * Strong AES-256 encryption in 7z and ZIP formats
 * Powerful command line version

note: "p7zip-full" package provides full-featured, but older 7-Zip archiver.
      This "7zip" package provides stand-alone style archiver only, but
      newer 7-Zip archiver.
      "7zip" package is in "non-free" section because "unRAR" code is not
      compatible with DFSG.

Current packaging state is held on https://salsa.debian.org/yokota/7zip .

目前在 Linux 上提供 7zip 的项目 p7zip 自从2016年起没有更新，而且目前没有人成功地联系到原作者。
p7zip 有一个活跃的分叉

然而，仅仅有少数分发（Arch Linux, OpenMandriva, Mageia and ALT Linux ）切换到该分叉，多数分发（包括Debian GNU/Linux）都没有切换到该分叉。
所以，我们可能会在 Linux 上看到竞争的两个 7zip 实现。 Debian 中会发生什么事情是不确定的，p7zip 包可能会切换到新上游，或者被移除。
