type CovDataReader …

// MakeCovDataReader creates a CovDataReader object to process the
// given set of input directories. Here 'vis' is a visitor object
// providing methods to be invoked as we walk through the data,
// 'indirs' is the set of coverage data directories to examine,
// 'verbosityLevel' controls the level of debugging trace messages
// (zero for off, higher for more output), 'flags' stores flags that
// indicate what to do if errors are detected, and 'matchpkg' is a
// caller-provided function that can be used to select specific
// packages by name (if nil, then all packages are included).
