+# Generates a POT file.
+#
+# Here is a translator work flow with the generator.
+#
+# == Create .pot
+#
+# You create .pot file by pot formatter:
+#
+#   % rdoc --format pot
+#
+# It generates doc/rdoc.pot.
+#
+# == Create .po
+#
+# You create .po file from doc/rdoc.pot. This operation is needed only
+# the first time. This work flow assumes that you are a translator
+# for Japanese.
+#
+# You create locale/ja/rdoc.po from doc/rdoc.pot. You can use msginit
+# provided by GNU gettext or rmsginit provided by gettext gem. This
+# work flow uses gettext gem because it is more portable than GNU
+# gettext for Rubyists. Gettext gem is implemented by pure Ruby.
+#
+#   % gem install gettext
+#   % mkdir -p locale/ja
+#   % rmsginit --input doc/rdoc.pot --output locale/ja/rdoc.po --locale ja
+#
+# Translate messages in .po
+#
+# You translate messages in .po by a PO file editor. po-mode.el exists
+# for Emacs users. There are some GUI tools such as GTranslator.
+# There are some Web services such as POEditor and Tansifex. You can
+# edit by your favorite text editor because .po is a text file.
+# Generate localized documentation
+#
+# You can generate localized documentation with locale/ja/rdoc.po:
+#
+#   % rdoc --locale ja
+#
+# You can find documentation in Japanese in doc/. Yay!
+#
+# == Update translation
+#
+# You need to update translation when your application is added or
+# modified messages.
+#
+# You can update .po by the following command lines:
+#
+#   % rdoc --format pot
+#   % rmsgmerge --update locale/ja/rdoc.po doc/rdoc.pot
+#
+# You edit locale/ja/rdoc.po to translate new messages.
