-
-This contains Haskell bindings to
-[libarchive](http://libarchive.org/). It was created as an alternative to
-[tar](http://hackage.haskell.org/package/tar) and
-[tar-conduit](http://hackage.haskell.org/package/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 `ByteString`s.
-
-## Hacking
-
-To run the test suite, first run
-
-```
-make
-```
-
-so that you have appropriate test data downloaded.
-
-## Performance
-
-`libarchive` is faster than `tar` or `tar-conduit` when unpacking archives.

- * Utility to match up hardlinks.
- *
- * The 'struct archive_entry_linkresolver' is a cache of archive entries
- * for files with multiple links.  Here's how to use it:
- *   1. Create a lookup object with archive_entry_linkresolver_new()
- *   2. Tell it the archive format you're using.
- *   3. Hand each archive_entry to archive_entry_linkify().
- *      That function will return 0, 1, or 2 entries that should
- *      be written.
- *   4. Call archive_entry_linkify(resolver, NULL) until
- *      no more entries are returned.
- *   5. Call archive_entry_linkresolver_free(resolver) to free resources.
- *
- * The entries returned have their hardlink and size fields updated
- * appropriately.  If an entry is passed in that does not refer to
- * a file with multiple links, it is returned unchanged.  The intention
- * is that you should be able to simply filter all entries through
- * this machine.
- *
- * To make things more efficient, be sure that each entry has a valid
- * nlinks value.  The hardlink cache uses this to track when all links
- * have been found.  If the nlinks value is zero, it will keep every
- * name in the cache indefinitely, which can use a lot of memory.
- *
- * Note that archive_entry_size() is reset to zero if the file
- * body should not be written to the archive.  Pay attention!
- */
-struct archive_entry_linkresolver;
-
-/*
- * There are three different strategies for marking hardlinks.
- * The descriptions below name them after the best-known
- * formats that rely on each strategy:
- *
- * "Old cpio" is the simplest, it always returns any entry unmodified.
- *    As far as I know, only cpio formats use this.  Old cpio archives
- *    store every link with the full body; the onus is on the dearchiver
- *    to detect and properly link the files as they are restored.
- * "tar" is also pretty simple; it caches a copy the first time it sees
- *    any link.  Subsequent appearances are modified to be hardlink
- *    references to the first one without any body.  Used by all tar
- *    formats, although the newest tar formats permit the "old cpio" strategy
- *    as well.  This strategy is very simple for the dearchiver,
- *    and reasonably straightforward for the archiver.
- * "new cpio" is trickier.  It stores the body only with the last
- *    occurrence.  The complication is that we might not
- *    see every link to a particular file in a single session, so
- *    there's no easy way to know when we've seen the last occurrence.
- *    The solution here is to queue one link until we see the next.
- *    At the end of the session, you can enumerate any remaining
- *    entries by calling archive_entry_linkify(NULL) and store those
- *    bodies.  If you have a file with three links l1, l2, and l3,
- *    you'll get the following behavior if you see all three links:
- *           linkify(l1) => NULL   (the resolver stores l1 internally)
- *           linkify(l2) => l1     (resolver stores l2, you write l1)
- *           linkify(l3) => l2, l3 (all links seen, you can write both).
- *    If you only see l1 and l2, you'll get this behavior:
- *           linkify(l1) => NULL
- *           linkify(l2) => l1
- *           linkify(NULL) => l2   (at end, you retrieve remaining links)
- *    As the name suggests, this strategy is used by newer cpio variants.
- *    It's noticeably more complex for the archiver, slightly more complex
- *    for the dearchiver than the tar strategy, but makes it straightforward
- *    to restore a file using any link by simply continuing to scan until
- *    you see a link that is stored with a body.  In contrast, the tar
- *    strategy requires you to rescan the archive from the beginning to
- *    correctly extract an arbitrary link.

- * that are supported by "pax interchange" format.  However, GNU, ustar,
- * cpio, and other variants don't support these features, so they're not an
- * excruciatingly high priority right now.
- *
- * TODO: "pax interchange" format allows essentially arbitrary
- * key/value attributes to be attached to any entry.  Supporting
- * such extensions may make this library useful for special
- * applications (e.g., a package manager could attach special
- * package-management attributes to each entry).  There are tricky
- * API issues involved, so this is not going to happen until
- * there's a real demand for it.
