Prefixing a shell command with zrun causes any compressed files that are
arguments of the command to be transparently uncompressed to temp files
(not pipes) and the uncompressed files fed to the command.
This is a quick way to run a command that does not itself support
compressed files, without manually uncompressing the files.
The following compression types are supported: gz bz2 Z xz lzma lzo
If zrun is linked to some name beginning with z, like zprog, and the link is
executed, this is equivalent to executing zrun prog.
