Bug#557883: lintian: false positive in lib-recommends-documentation (name vs. content)

[Jay Berkenbilt <qjb@debian.org>]

Package: lintian
Version: 2.2.18
Severity: normal

*** Please type your report below this line ***

lintian is reporting lib-recommends-documentation on the libvips-tools
package.  This is a false positive because libvips-tools is not a
library package.  Perhaps it should be called something different, like
vips-tools, but I think the real problem is that lintian is assuming a
library package based on the package name rather than the package
contents.  The libvips-tools package contains no .so.* files.  In fact,
it doesn't even contain any lib directories.

I think this test would be better implemented to check the contents of
the package looking for /usr/lib/*.so.* files rather than doing a regexp
on the name and trying to special-case out -dev and -doc packages, which
seems rather fragile to me.  I imagine there will be many false
positives otherwise.
