    Default ANNOUNCEMENT: Compress::Bzip2 2.08

    Compress::Bzip2 2.08 has been released.

    Features:
    =========

    * built on top of bzip2 1.0.2

    * extensive set of unit tests.

    * a new file I/O interface with bzopen, bzread, bzwrite, bzclose, etc.

    * a new stream interface.

    * compatibility with Compress::Bzip2 1.03

    * a Compress::Zlib clone interface, so that programs built for
    Compress::Zlib should work with Compress::Bzip2 with no changes,
    simply replace use Compress::Zlib; with use Compress::Bzip2
    qw(:gzip);

    * includes bzip2 1.0.2 source code, so that it will build on systems
    without bzip2 installed. The build process tests for the presence
    of a useable installation of bzip2. If none is found, the internal
    source code is used. If bzip2 is not installed in a standard
    location, the correct location can be specified either with
    environment variables or with a config file.

    Bug fixes:
    ==========

    * previous versions were either not functional or not interoperable
    with bzip2 when dealing with files larger than the internal buffer
    size (100k to 900k). The 2.x series uses the logical eof rollover
    method described in the bzip2 docs.

    What is Bzip2 ?
    ===============

    Bzip2 is a portable lossless data compression library written in ANSI
    C. It offers pretty fast compression and fast decompression. Bzip2
    has very good results, if you want to compress ASCII Doents.

    Bzip2 is probably not great for streaming compression. It fills it's
    internal buffer, which depending on parameters is between 100k and
    900k in size, before it outputs ANY compressed data. It works best
    compressing an entire doent.

    Streaming decompression on the other hand, gives a steady torrent of
    bytes.

    Default ANNOUNCEMENT: Compress::Bzip2 2.08

    Text::Statistics::Latin 0.04 has been released.

    Description:


    Text::Statistics::Latin creates a seven column CSV file output with
    one line each
    token per text, given as input an utf8-latin coded corpus that files
    names follows:
    1 (1). txt', '1 (2). txt', ..., '1 (n).txt' or the pattern
    1 \(([1-9]|[1-9][0-9]+)\)\.txt
    Columns stores statistical information:
    (1) number of word forms in doent d;
    (2) number of tokens in d;
    (3) Id number of d, ie., n;
    (4) frequency of term t in d;
    (5) corpus frequency of t ;
    (6) doent frequency of t (number of doents where t occurs at
    least once);
    (7) t, UTF8 latin coded token-string

    Main output file name is '1 (n + 5).txt' and it is stored in the same
    directory as the corpus itself, together with residual files on each
    input file with .txu and .txv ad hoc extensions.

    Example:
    use Text::Statistics::Latin;
    &LATIN("4"); #3 (4-1) texts will be ised.

    Note:

    (1) 1 \(([1-9]|[1-9][0-9]+)\)\.txt is the pattern Windows Explorer
    uses when renaming sets of files.
    (2) This module can be used for testing information retrieval
    weighting functions or text indexing.
