developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
In general, your tests shouldn't produce warnings. This modules
causes any warnings to be captured and stored. It automatically
adds an extra test that will run when your script ends to check
that there were no warnings. If there were any warnings, the test
will give a "not ok" and diagnostics of where, when, and what the
warning was, including a stack trace of what was going on when it
occurred.
If some of your tests are supposed to produce warnings then you
should be capturing and checking them with Test::Warn, that way
Test::NoWarnings will not see them and so not complain.
