The zip-archive library provides functions for creating, modifying, and
extracting files from zip archives. The zip archive format is documented in
<http://www.pkware.com/documents/casestudies/APPNOTE.TXT>.
Certain simplifying assumptions are made about the zip archives: in particular,
there is no support for strong encryption, zip files that span multiple disks,
ZIP64, OS-specific file attributes, or compression methods other than Deflate.
However, the library should be able to read the most common zip archives, and
the archives it produces should be readable by all standard unzip programs.
Archives are built and extracted in memory, so manipulating large zip files
will consume a lot of memory. If you work with large zip files or need features
not supported by this library, a better choice may be
<http://hackage.haskell.org/package/zip zip>, which uses a memory-efficient
streaming approach. However, zip can only read and write archives inside
instances of MonadIO, so zip-archive is a better choice if you want to
manipulate zip archives in "pure" contexts.
As an example of the use of the library, a standalone zip archiver and
extracter is provided in the source distribution.
