Package: gzip
Version: 1.14-1~exp2ubuntu1
Severity: wishlist
X-Debbugs-Cc: [email protected]
Dear Maintainer,
Right now, the autopkgtests for gzip are very simple, just a roundtrip
compress/decompress
of an extremely trivial file. The attached patch (forwarding upstream from
Ubuntu) adds a
some more tests for more advanced usage (mutlifile (re)compression and envar
support).
