+.B Red Hat Linux Users Please Note:
+RH Linux (and possibly other Linux systems) install two versions of
+Python.  Version 1.52 is called \'python\', and Version 2.2 is called
+\'python2\'.  \'twander\' requires the latter and will not run on the
+former.  As shipped, \'twander\' invokes Python with the Unix shell
+"#!" mechanism using the name \'python\' - which in this case is the
+wrong version.  You can work around this problem one of several ways:
+
+.IP \(bu 4
+Rename \'python\' to \'python1\' and then rename \'python2\'
+to \'python\'. (Not Recommended - could break other programs.)

+Write an alias or shell script which explicity starts
+\'twander\' with the correct version of Python:

+Change the first line of the \'twander\' code to refer

+Red Hat users who have upgraded from earlier versions should
+also note that you may have files in your home directories owned by
+owners and groups which are not defined in the system!  \'twander\'
+shows the owner and group fields for such files as numbers rather than
+names.  As best as we can determine, this is caused when an RH
+installation is updated from an older version.
