It requires headers and libraries for Boost, gtkmm, Mozilla or
-XULRunner, and expat. I have developed and tested it with Boost 1.32,
-gtkmm 2.2.12, Mozilla 1.7.8 and expat 1.95.8 but it may well work with
-earlier or later versions of these. I have also tested with Mozilla
-1.7.12 and XULRunner 1.8.0.5.
+XULRunner, and expat. I am currently building and testing it with
+Boost 1.33, gtkmm 2.8.8, XULRunner 1.8.0.11 and expat 1.95.8. It may
+well work with earlier or later versions of these, but Mozilla 1.7
+and gtkmm 2.0 and 2.2 are no longer supported.
I use Debian Linux and have not yet attempted to build it on other
systems, but it should work on most modern Unix-like systems.
