IPC::Pipeline 0.4

    * Pare down superfluous bits of IPC::Pipeline

    * Maximize unit test coverage, excluding any portions which test code
      that would run in a subprocess

    * Implicitly use POSIX module without an import() call

    * Only list Test:: dependencies as build-time dependencies in
      Makefile.PL

    * Minor tweaks to code for style, consistency, and a small unchecked
      exec() bug

    * Implement support for executing CODE refs as parts of a pipeline

    * Improve and reorganize documentation into smaller sections

IPC::Pipeline 0.3

    A release to fix documentation which was inconsistent with the previous
    implementation regarding the way the file handle positional parameters
    were being handled.  This also fixes the code to allow receipt of file
    typeglobs, numeric file descriptors, and the usual positional scalar
    substitution method.  Note that an implicit dependency upon POSIX::dup2()
    is now made if numeric file descriptors are passed, as a workaround to
    undesirable multiple calls to the dup2() system call by Perl's open()
    when used in the expected (but unexpectedly resultant) manner.

    Some 80-column comment tweaks are also made in this release.

IPC::Pipeline 0.2

    Initial release, 2 June 2010.
