What is a .pot file?
text/x-gettext-translation
A POT file (.pot, Portable Object Template) is a gettext template — a PO file with all msgstr values left empty. It is generated from source code by string extraction (xgettext) and is copied to start a new language's .po translation. Its header carries the plural-forms rule and project metadata.
How to use a .pot file
Use an example .pot template to test string-extraction pipelines, PO initialisation (msginit), and tools that create or update per-language catalogs from a template.
