Source: cd-hit
Version: 4.6.7-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that cd-hit could not be built reproducibly.

This is because the help2man call to cd-hit-div fails as it does not
support --help argument, and the error message contains the absolute
build path.

Patch attached. It adds a very basic "usage" stanza, thus fixing both
issues at once.
