All reports of shlibs-uses-obsolete-relation for the archive. The extended description of this tag is:
The forms "<" and ">" mean "<=" and ">=", not "<<" and ">>" as one might expect. For that reason these forms are obsolete, and should not be used in new packages. Use the longer forms instead.
Refer to Debian Policy Manual section 7.1 (Syntax of relationship fields) for details.
