Thread:User talk:Sumanah/Missing i18n: identification of “need to translate” strings

From a very proprietary point of view, this thesis mentions: «If source code is available, tools and techniques, with varying quality of internationalization, can be used to internationalize an existing monolingual product that minimize costs and improve efficiency. This includes the use of lexical analysis as shown by Peng et al., automated identification of “need to translate” strings as shown by Wang et al., and the use of tools like GNU Gettext. See 4.4.5 and 4.5 for details.» http://publications.lib.chalmers.se/records/fulltext/161183.pdf
