INSTALLATION
------------

First, you'll have to get the dependencies. Make sure to install the header
files for the libraries (on Debian and derivatives, headers are in `-dev`
packages, e.g. `libsqlite3-dev`.) After that, compiling and installing newsboat
is as simple as:

	$ make
	$ sudo make install

And if you ever need to uninstall it, use `make uninstall`.

Cross-compilers need to set `CARGO_BUILD_TARGET`; see [cargo
documentation](https://doc.rust-lang.org/cargo/reference/config.html#environment-variables).
