4. Making the PO Template File
After preparing the sources, the programmer creates a PO template file.
This section explains how to use xgettext for this purpose.
xgettext creates a file named `domainname.po'. You
should then rename it to `domainname.pot'. (Why doesn't
xgettext create it under the name `domainname.pot'
right away? The answer is: for historical reasons. When xgettext
was specified, the distinction between a PO file and PO file template
was fuzzy, and the suffix `.pot' wasn't in use at that time.)
