README excerpt:

  This is the Guile WWW library, a set of Guile Scheme
  modules to facilitate HTTP, URL and CGI programming.

NEWS excerpt:

  - 2.34 | 2012-03-29

    - bug fix: unbotch ‘upath->filename-proc’
    - bug fix: unbotch ‘log-http-response-proc’

        In Guile-WWW 2.33 (2012-02-29), these procs were changed to use
        (ice-9 optargs), but the change was botched.

    - bug fix: ‘(www http) http:post-form’ reserves ‘#\&’ and ‘#\=’

        That is, in the absense of upload specs, the urlencoding for the
        key names and values now also includes ampersand and equal sign,
        as those used to delimit pairs and separate key and value within
        a pair, respectively.

    - bug fix: ‘url-coding:encode’ outputs two hex digits for 0-15

        Previously, octets 0 through 15 were output as "%0" through
        "%f", respectively.  Now, they are "%00" through "%0f".

    - portability fix: big dishing loop handles #f ‘sockaddr:path’

        For Unix domain sockets, some Guile versions have ‘sockaddr:path’
        sometimes return the empty string, others ‘#f’.

    - ‘(www url) url:parse’ can handle IPv6 addresses

        Handling doesn't imply validation, however.  For example:
        (url:host (url:parse "http://address@hidden::ffff:bogus.0.2.1]:42/foo";))
        => "[::ffff:bogus.0.2.1]"

    - ‘(... answer) hqf<-upath’ more efficient

        The char-set computation has been moved to load-time.

    - ‘(... cookies) simple-parse-cookies’ takes optional arg SEP

        By default, tokens are ‘#\,’ (comma)-separated.  You can use SEP
        to specify another character, e.g., ‘#\;’ (semicolon).

    - new ‘(www cgi) cgi:init’ option: cookies-split-on-semicolon

        If the server provides the CGI script with a "Netscape style"
        (i.e., old and deprecated) set of cookies, you can use this
        option to split them.

    - ‘(www cgi) cgi:getenv’ recognizes some more "idiomatic" names

        The following keys now are recognized by ‘cgi:getenv’ (that is,
        they no longer signal "unrecognized key" error): ‘server-name’,
        ‘server-software’, ‘server-protocol’, ‘auth-type’, ‘http-accept’.
        Also, the manual now marks those keys that either are aliases,
        or return parts of the associated value, of these idiomatic names.

    - new (... parse-request) proc: receive-request

        This uses the same underlying machinery as ‘receive-response’
        from (www http), and thus sports the same features.

        Additionally, there is a new ‘request’ type with five accessor
        procs: request-{method,upath,protocol-version,headers,body} and
        the new predicate ‘request?’.

    - new (... log) proc: string<-sockaddr

        This formats AF_UNIX or AF_INET addresses (including port).

    - new (... answer) proc: compose-response

        This is a stripped down variant of ‘mouthpiece’.  It uses the
        same underlying machinery as ‘send-request’ from (www http) and
        thus sports the same features.

    - MARKED FOR REMOVAL

      - 2012-12-31 module (www main)

      - 2012-12-31 (www url) procs
        - url:address
        - url:unknown

      - 2013-02-28 (... parse-request) procs
        - read-first-line
        - read-headers
        - skip-headers
        - read-body

      - 2013-02-28 (www http) procs
        - http:head
        - http:get

    - test suite expanded

        Previously, there was just one test.  Now, there are several,
        and they are in directory v/ (for "validation", "verification",
        "vouchsafed", and so on).
