gpg-agent is older than us

[Ajax]

Thank you Phil,
/usr/bin/gpg-agent is started by systemd and I think it should be left
as it is for the Debian package manager to use with /usr/bin/gpg.  Why
cannot ~/bin/gpg use ~/bin/gpg-agent?  Is it true that gpg in $HOME or
/usr/local should work independently from /usr/bin/gpg?
