Inuse is a graphical memory monitor that aids in visualizing and understanding dynamic memory manipulation.
Documentation is lucid and well partitioned.
Both Inuse and TCA manuals are slim and to the point. The corresponding GUIs are self-descriptive. The reference manual is handy, as it clearly illustrates the error codes with actual problem scenarios and ways to fix them. The section on interfaces in the user's manual is well written and useful. Insight Insight is a source-level automatic runtime debugging tool.
