Comment 1 for bug 697008

APT can't find it as the long description only is:
> Description: Utilities for building FreeBSD sources
> This package contains the FreeBSD counterparts of some standard build
> utilities (make, yacc, lex ..)
> .
> They have some specific modifications needed to be able to build FreeBSD
> sources (such as kfreebsd-8).
(at least that is the description for debians version 8.1-1)

Nothing about mtree, so mtree can't be found.

Please ask the package maintainer to include whatever would be useful
in the description. A '..' (what should be a '...' or better '…') isn't useful
in this case as a program can't make the needed mental transformation…

Just in case:
$ apt-cache search yacc
and
$ apt-cache search yacc freebsd
have the expected results.

Best regards
