+"""
+Ivanovic's original specification from FR #9039.
+
+ would be nice to have a tool maybe named utils/textdomain2textdomain
+ that is able to change the textdomain of a given campaign. The params
+ that the script should support are these: campaignname,
+ oldtextdomain, newtextdomain
+
+    * asumptions: campaign lies in data/campaigns, current textdomain
+      is wesnoth-oldtextdomain, the translation files are existing
+      (and maybe already uploaded) in the folder
+      /po/wesnoth-oldtextdomain/.
+
+Here is what is too be done for the campaign named 'foo' to move from
+the textdomain wesnoth-oldtextdomain to wesnoth-newtextdomain:
+
+1) search in all files in data/campaigns/foo* (yes, the .cfg file, too) for this string:
+
+#textdomain wesnoth-oldtextdomain
+
+2) replace (be aware, there might be " " around the part after name=)
+
+[textdomain]
+name=wesnoth-oldtextdomain
+[/textdomain]
+
+with
+
+[textdomain]
+name=wesnoth-newtextdomain
+[/textdomain]
+
+3) move the folder po/wesnoth-oldtextdomain to
+   po/wesnoth-newtextdomain (svn mv if the file is already under
+   version conrol, normal mv if it is not)
+
+4) move the file (folders are already changed)
+   po/wesnoth-newtextdomain/wesnoth-oldtextdomain.pot to
+   po/wesnoth-newtextdomain/wensoth-newtextdomain.pot (via svn mv if
+   files are under version control already, --force will be needed,
+   since it is a 2nd move)
+
+5) replace wesnoth-oldtextdomain by wesnoth-newtextdomain in
+   po/wesnoth-newtextdomain/Makevars
+
+6) replace wesnoth-oldtextdomain by wesnoth-newtextdomain in po/Makefile.am
+
+7) replace wesnoth-oldtextdomain by wesnoth-newtextdomain in configure.ac
