I'm actually having trouble accessing the sources. The invocation

cvs -z3 -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/m17n 
co m17n

as described at <http://savannah.nongnu.org/cvs/?group=m17n>

just gives me an empty CVS repository. Substituting `m17n-lib' for 
`m17n' does seem to checkout the sources, but the newest source 
files there are from 2014. (Which is why I said "seem to check out 
the sources", but I have no experience with CVS, so I may be doing 
something silly.)

According to <https://www.nongnu.org/m17n/>, that would correspond 
to version 1.17, released in 2014, which also happens to be the 
version installed on my Linux system (which is based on Ubuntu 
16.04). That www page also lists a version 1.18, from February of 
this year. I can try and install that, if you think it makes 
sense.

(Actually, the package installed on my system is called libm17n, 
not libm17n-flt, not sure if that matters.)

TIA
