 MetaGlot is a command-line tool that unifies localization metadata for applications shipped on multiple platforms. It extracts or defines translatable strings from platform-specific metadata files, normalizes them into Gettext-compatible POT/PO catalogs, and compiles translated PO files back into platform-native files.
 
-It currently is designed for projects that ship on:
-
-- **Windows** using RC resource files
-- **Linux** using `.desktop` and AppStream MetaInfo XML files
-- **macOS** using `Info.plist` and localized `InfoPlist.strings` files
+It currently is designed for projects that ship on Windows, Linux and macOS.
