		<p>

			Instalation was tested on Debian GNU/Linux 9.6.

			The process should be similar on other distributions.

		</p>

		<p>

			<m:name/> are modular thus you can download and install only parts you need (the libraries are needed always).

			Tools <code>out-gui.qt</code> and <code>tr-python</code> require additional libraries and are not built by default.

		</p>

		<p>

			The module <code>relpipe-in-filesystem</code> uses C++ filesystem API which is supported since GCC 8.

			This module can be compiled and seems usable even with GCC 6, but requires some patching (switch to the experimental API):

			The module <code>relpipe-tr-guile</code> uses GNU Guile 2.2 but can also work with 2.0.

			In such case, it requires this patch:
