// runbook.C
// =========
//
// This is an example macro how to extract the runbook information of
// a given date from the runbook files.
//
// The argument is a date in regexp format, eg.
//   .x runbook.C("2004-05-1[0-9]")
//
// With an MDirIter you can tell the macro which directories and files
// should be searched.
//
// The output are the runbook entries matching your query.
