I should never be surprised by PerlMonks, but I was surprised by how many nodes cover "topological sort"s:

• Sort Algorithm (recursive?)
• Task scheduling using perl
• Dependency Inference
• How do I use Graph::Traversal?
• In search of an algorithm for loading cyclic graphs
• Order your autobundle by dependency
• The Lighter Side of Perl Culture (Part IV): Golf
• Problems with sorting
• Priority Sorting Challenge
• "Intelligent" array joining
• Parse C-like define statements
• Rolling a biased die
• where do you put your subs
• Sorting, given only comparisions
• Topological Sort in Perl
• Gantt Diagrams

The best subtitle, however, simply must go to Gantt Diagrams... ;-)

HTH,
