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.
cqual is a type-based analysis tool for finding bugs in C programs. It
extends the type system of C with extra user-defined type qualifiers.
The programmer annotates their program in a few places, and cqual
performs qualifier inference to check whether the annotations are
correct.
