All reports of description-synopsis-might-not-be-phrased-properly for the archive. The extended description of this tag is:
The package synopsis (also known as the "short" description, ie. the first line in the package's "Description:" field) either ends with a full stop "." character or starts another sentence.
This is not necessary as the synopsis does not need to be a full sentence. It is recommended that a single descriptive phrase is used instead.
Note also that the synopsis is not part of the rest of the "long" Description: field.
Refer to Debian Developer's Reference section 6.2.2 (The package synopsis, or short description) for details.
This tag has not been emitted in any package tested by Lintian.
