…why? Because show_changes will become the "do you want to install
this?" confirmation at some point. That's not what it does now, it just
shows you the version for now. But eventually it will tell you the
version you have installed, compare to the version you are going to
install, show you the changes between here and there, and ask you if you
actually want to proceed with installation. When that happens it'll be
appropriate to rename the script, but for now it's a placeholder.
Do not put this hash into production without the following one!
As with a2server, I've written a new setup.txt that downloads the entire
a2cloud source tree for installation, which allows the monolithic script
to be broken up into smaller pieces without worrying about that breaking
the web install—but it's not included in this revision so that git can
keep track of the rename of setup.txt to ivan.sh.
Despite the fact there is no 2.0.0 release yet, 1.9 is already so close
that it doesn't give Ivan any breathing room for any patches he wants to
make, so my intention is to skip major version 2 entirely other than for
this transition. The final release will be given the 3.0.0 version
number.
