0.6  2018-05-09
        - Re-allow relative paths (was broken in 0.5).  Otherwise common
          POTFILES files cannot be read.
        - Allow argument to --plug-in to be empty so that you can extract
          arguments from functions in the TT2 root namespace. 
0.5  2018-03-27
        - Template::Plugin::Gettext now automatically sets the utf8 flag
          on translated strings, when the original string (the msgid) had
          the utf8 flag set.
        - xgettext-tt2 can now be used without a plug-in, i. e. for functions
          in the root namespace.
