ADMIN: please do not crosspost, list purpose

[Greg Troxel <gdt%lexort.com@localhost>]

We have two discussion lists for pkgsrc, and there has been a signifcant
amount of crossposting, which defeats the purpose of separation.

Please do not crosspost to pkgsrc-users and tech-pkg.  If you are
tempted to crosspost, or unsure which list to choose, please use only
pkgsrc-users.  If you reply to a crosspost, please trim to one list when
replying.

tech-pkg is for discussion of proposed changes to files under pkgsrc/mk
and structural, wide-ranging, or high-consequence issues within pkgsrc.
(It is understood that the line between pkgsrc-users and tech-pkg is a
bit hard to draw, and that's ok.)

Greg, on behalf of pkgsrc PMC
