How to install

You need to install the Rust toolchain (rustup, cargo, etc) to build this program. You will also need scdoc to generate the manual pages, and make if you want to automatically build and install the program.

You can build it yourself using cargo:

cargo build --release

Or build it and install it using make:

make
sudo make install

You can remove it by executing:

sudo make uninstall

For more information about the usage of this program, see man 1 finbudg and man 5 finbudg after building and installing with make.
