Lintian tag information: obsolete-relation-form (type: warning)

Description (from lintian-explain-tags)

The short version restrictions < and > actually mean <= and >= (and not <<
or >>, as one might expect).

The short forms are obsolete and should no longer be used. Please use the
longer forms in the parentheses instead.

Please refer to Syntax of relationship fields (Section 7.1) in the Debian
Policy Manual for details.
