###################################################################### Proc::Simple CHANGES ###################################################################### from 1.25: Localize special variables so that the exit status from waitpid doesn't leak out, causing exit status to be incorrect (RT33440, fixed by Brad Cavanagh). from 1.24: Added copyright header from 1.23: Applied doc patch by Janne Chr. Schulz from 1.22: Applied patch by Jeff Holt, providing start and end time of the forked process via t0() and t1(). from 1.21: Added patch by Chip Capelik to provide a wait() method waiting for a process to terminate. from 1.20: Added patch by Tobias Jahn <tjahn@users.sourceforge.net>, to redirect STDOUT or STDERR of the child process upon request. from 1.19: Fixed bug which occurred on failed fork()s, as reported anonymously on the CPAN bug tracker. from 1.18: Added multi-arg start method (proposed by Clauss Strauch <Clauss_Strauch@aquila.fac.cs.cmu.edu>) from 1.17: Fixed Version difference between Makefile.PL and Simple by using VERSION_FROM (thanks Andreas Koenig) from 1.16: Fixed bug with Proc::Simple instances which were DESTROYED before they were ever started. Many thanks to Russell Fulton (r.fulton@auckland.ac.nz) for pointing this out. from 1.15: Added %DESTROYED hash for processes which might still in zombie state right after their objects went out of business. THE_REAPER will take care of them. from 1.14: Added exit_status() method and a smart REAPER which reaps only processes we've started before. from 1.13: Replaced two erronous uses of 'exists' by 'defined'. Thanks to Rolf.Beutner@telekom.de for pointing this out. from 1.12: To fight problems with zombies, replaced the wait() function by a NOWAIT waitpid on systems that support it. Tim Jenness <t.jenness@jach.hawaii.edu> included kill_on_destroy/sig_on_destroy/pid methods. from 1.11: binkley's error: threw out waitpid, wait is performed by signal handler now. from 1.1: Process is now called Proc::Simple to fit in the CPAN namespace, corrections Andreas Koenig suggested.
