MS/DOS-compatible archivers

[Wally Hartshorn]

In the MS/DOS world (and, for that matter, the Amiga world) the most
common file compression formats are ARC, ZOO, ZIP, and LZH.  I know that
there is a UNIX version of ZOO that is file-compatible with the MS/DOS
versions.  Are there UNIX versions of ARC, ZIP, and/or LZH (aka Lharc)?
If so, could someone point me in the proper direction to get them?

Thanks in advance.
