- Packs an archive. It is the opposite of M(unarchive). By default, it assumes the compression source exists on the target. It will not copy the

source file from the local system to the target before archiving. Source files can be deleted after archival by specifying I(remove=True).

notes:
|
|
- requires tarfile, zipfile, gzip and bzip2 packages on target host
|
|
- requires lzma or backports.lzma if using xz format
|

- can produce I(gzip), I(bzip2), I(lzma) and I(zip) compressed files or archives
