<h1>Troggle - Fixing things that break</h1>
<p>The guide to the parser-model-view architecture is in the architecture document.
<p><em>This page will describe the usual things that go wrong: the parsers that break when
faced with user-generated data and how to fix them. Common error messages. </em>
<p>It concentrates on showing how to find and fix import errors so that the troggle-generated webpages are complete and not full of gaps.

<p><b>Intended audience:</b> Ideally someone who is not a python programmer will be able to use this page to help them 
fix import errors by re-editing the input files: survex, tunnel, or logbook.

<p>These are the useful diagnostic detailed data pages for finding mis-matched files. This page will show you how to use these together to find 
data inconsistencies and to fix errors.<br>
