aqua-proxy
https://github.com/aquaproj/aqua-proxy
The internal CLI tool of aqua.
We develop aqua-proxy for aqua, and we don't assume that aqua-proxy is used in the other purpose.
Basically the user of aqua don't have to know the detail of aqua-proxy.
aqua-proxy is installed to $AQUA_ROOT_DIR/bin/aqua-proxy
automatically when aqua install
and aqua exec
is run, so you don't have to install aqua-proxy explicitly.
aqua-proxy has only the minimum feature and responsibility. aqua-proxy is stable and isn't changed basically.
aqua-proxy is developed to decide the version of aqua and package managed with aqua dynamically according to the aqua's configuration file when the package is executed.
Please see How does Lazy Install work? too.
