I like the idea and will look into applying the patch
(note there's at least one typo which makes "make check" fail:
/priotiry/)
A propos:
A while back (in last summer?), we (some of R-core) have
discussed about a new field to be added to DESCRIPTION,
and AFAIR, the only problem we had, is to find a name we
all liked.
Or was there more then the name alone, and some where convinced
that it is superfluous and hence too complicated.
The idea was a field related to but weaker than 'Suggests' :
Something like
'canMakeUseOf: <pkg1> [, <pkg2>, ... ]
which is *not* used in any QA/QC checking, but is purely
informative: If <pkg1> is require()able, then some examples may
look nicer, a function may provide another feature, etc, etc.
Alternatives to 'canMakeUseOf' would have been
'isHappilyCoworkingWith' ....
What do you (R-devel listeners) think about the idea?
