# @ /par Internationalization.
# @ /note The simulator and utilities will use the GNU gettext library to do localization
# @ and internationalization for both windows and linux. The primary
# @ tool used will be poEdit. The build process will contain a job (INTERNATIONALIZATION)
# @ that will gather strings and add then to the source files in the internationalization
# @ sub-directory of src (trunk/src/internationalization).
# @ This file is a combination of wxstd.po and the strings gathered from the utilities.
# @ This po source will install on the user machine with instruction to
# @ get poEdit to facilitate translations.
