wmtop-0.84
>Description:
wmtop gets process information via procfs, but FreeBSD 5.x doesn't mount it by default. The 5.x users won't see any process shown by wmtop unless they mount procfs for some reasons.
>How-To-Repeat:
Install and run wmtop on 5.x machines without procfs mounted.
>Fix:
The following patch fixes the problem described above. Also thank rafan <rafan at infor.org> for the PORTDOCS fix.
