Installation

You can install frugalos by the following command:

$ cargo install frugalos

Note: The current installation process requires automake, autoconf, and libtool to build liberasurecode internally. If you have not installed them, please install them. (See also liberasurecode's prerequisites)

You can also use pre-build binaries from the releases page.
