This contains Haskell bindings to libarchive. It was created as an alternative to tar and tar-conduit, but it supports more archive formats.
It has a high-level Haskell API for creating and unpacking archives in addition
to the C API. Like the tar package, it can stream from lazy ByteStrings.
To run the test suite, first run
make
to download test data.
libarchive is faster than tar or tar-conduit when unpacking archives.
