This is the source code for my personal website you can find under philippmoers.de.
Edit source in src.
Build with ./build.sh.
Copy generated target directory to your webserver (I use ./upload.sh for that).
Translations for multiple languages are managed with the GNU gettext system.
Translations files are generated, this is done as a build step (see above).
Note that translations may be cached, so you may have to restart the webserver.
