ChangeLog:
0.040	2007-12-26
	major rewrite of pod:
	  - describe all possible forms of redirectors
	  - list available options
	  - explain how run3() works
	fix #31343 by using the three argument form of open() for files;
	  unfortunately that isn't available before Perl 5.6.0,
	  hence "use 5.006_00"; also use lexical filehandles everywhere
	implement options append_{stdout,stderr}; add test cases
	edit META.yml so that the profiling modules IPC::Run3::Prof*
	  (which aren't of general use) won't show on CPAN
