new programmes should NOT use Nanomsg.
+Manual Pages
+By default the deb created does not include the manual pages. To
+enable their creation, and subsequent inclusion in the deb, add
+the following option to the cmake command:
+
+ -DBUILD_DOC=1
+
+This will cause the {X}fm text formatting package to be fetched
+(github) and built at cmake time (must exist before building)
+and will trigger the generation of the man pages in both postscript
+and troff format. The troff pages are placed into the deb and
+the postscript pages are left in the build directory for the
+developer to convert to PDF, or otherwise use.
