CHANGELOG

note:
	- Playback will fail if PCM is used and target device requires MP3 conversion (eg it is a bridge) 
	because the lame conversion rule expects a wav file which means a header. 
	- BEWARE OF VERSION NUMBER FOR PERL LIBS
	- to create perl libs
		perlbrew install --multi --64int --thread --notest -j 4 perl-x.yy.z (add -Dcc=gcc on solaris)
		source ~/perl5/perlbrew/etc/bashrc
		perlbrew switch perl-x.yy.z
		
		cpan -T Crypt::OpenSSL::RSA
		cpan -T Crypt::Ed25519
		cpan -T CryptX
		
		with version number:
		
        cpan -T MLEHMANN/Crypt-Ed25519-1.04.tar.gz
		cpan -T TODDR/Crypt-OpenSSL-RSA-0.30.tar.gz
		cpan -T MIK/CryptX-0.060.tar.gz
		(on Solaris and a few debian - arm & aarch64 now, need to specify mirror -M https://cpan.metacpan.org before the lib name)
	- on FreeBSD, use cshrc instead of bashrc or launch bash before "sourcing"
