This template is used to extract the first paragraph from a given text. If the first paragraph of the text is longer than 1000 characters, only the first 997 characters are returned, and an ellipsis (…) is added.
NOTE: As any "printing" template, it doesn't store any values anywhere, but merely returns them.
Parameters:
|vartext=- the text to extract the first paragraph from.
