Description

Expands a file packed using GZip or BZip2.

If dest is a directory the name of the destination file is the same as src (with the ".gz" or ".bz2" extension removed if present). If dest is omitted, the parent dir of src is taken. The file is only expanded if the source file is newer than the destination file, or when the destination file does not exist.
