No idea about automake integration, packaging, installation: adjustments in $/configure.ac regarding EM_LOCALIZATION_DIR, but there's also an localedir. L10n is supposed to be installed for a local setup, manual installation into system directories and automatic installation by distro package installation.
May break build for Microsoft Windows
Unable to make layout decisions based on the current locale (yet?)
