libpipeline 1.2.3 (24 April 2013)
=================================

Don't read uninitialised memory when testing for the end of long lines (over
4096 bytes).

Flush stdio before starting a sequence.

libpipeline 1.2.2 (17 September 2012)
=====================================

Make pipeline_start flush stdio after emitting debugging output.

Build fixes for glibc 2.16 and Automake 1.12.

libpipeline 1.2.1 (2 March 2012)
================================

Retry reads and writes on EINTR.

Fix opening of output files requested by `pipeline_want_outfile'; these are
now created if they do not already exist, and truncated if they do.

<pipeline.h> is now wrapped in `extern "C"' when used in a C++ compilation
unit.

libpipeline 1.2.0 (18 March 2011)
=================================

Add `pipeline_get_pid' to get the process ID of a command in a started
pipeline.

libpipeline 1.1.0 (11 December 2010)
====================================

Add `pipecmd_exec' to execute a single command, replacing the current
process; this is analogous to `execvp'.

Add `pipecmd_clearenv' to clear a command's environment; this is analogous
to `clearenv'.

Add `pipecmd_get_nargs' to get the number of arguments to a command.

libpipeline 1.0.0 (29 October 2010)
===================================

This is a new C library for pipeline manipulation, broken out from man-db
2.5.8.
