2. Source installation of libmrss and libnxml
---------------------------------------------

To date (2020-03-22) dist packages are not available
for libnxml and libmrss.  The tagged revisions
available on Github (user "bakulf") are not accompanied
by the corresponding release archives, and therefore
they depend on GNU Autotools.

For this reason I created the dist packages for both
libraries, and I published them as (unofficial)
release:

- https://github.com/dacav/libnxml/releases/download/0.18.3/libnxml-0.18.3.tar.gz
- https://github.com/dacav/libmrss/releases/download/0.19.2/libmrss-0.19.2.tar.gz
