Please see the Petal i18n documentation and the i18nFool documentation on CPAN for an introduction to internationalising MKDoc templates and the translation how to for instructions for translators.
These instructions are based on working with the default 1.8 templates with MKDoc 1.8 installed in /usr/local/mkdoc-1-8/ — change the paths to suite.
First move to the locale directory and generate a list of all the templates and pass this to in18fool-extract to generate the .pot file(s)
cd locale find /usr/local/mkdoc-1-8/resources/templates/ \ | egrep '\.(xml|html)$' | xargs i18nfool-extract
Create directories for each language and run i18nfool-update to update / generate the .po files
mkdir {en,fr,de}
i18nfool-update
Then build the .mo files
i18nfool-build
