+The file format is a simple line based plain text format with no limit on +line lengths. The file is indented with spaces to indicate the tree +structure. Indentation is stable in the export code, so parsers may depend +on it. However, it's probably more practical to depend on the fact that +the first 1 or 2 words in each line is a string literal that determines the +meaning of the line. Long blocks of embedded data are packed in between +begin/end markers. Begin marks often have human readable explanation at the +end of the line, those shall be ignored by parsers. Other than these, there +are no comments in the file. Empty lines shall be ignored. String literals +are written in bold in this document. +
+The first line of the file is Simulation setup: followed by the user +assigned name of the simulation setup being exported. There is exactly one +simulation setup exported per file. +
+Then comes one or more output trees. The output starts with an +Output: line conaining the user assigned name of the output. +Each output tree has three subtrees: analysis, presentation and data. +
+The analysis subtree is introduced by the analysis line. A config +subtree follows, to describe the analysis configuration. +
+The presentation subtree is introduced by the presentation line. +A config subtree follows, to describe the presentation configuration, +then a props subtree lists the columns of data. +
+The props subtree is ontriduced by a props begin line, followed +by 1 or more props, terminated by a props end line. The first prop is +always x: followed by the human readable label of the X axis. The +rest of the props are names of the data columns (y coords). +
+A config subtree is specified in between a pair of config begin and a +config end lines and contains zero or more key=value lines. +
+The data subtree starts with data begin and ends with data end. +It contains an arbitrary number of ordered data rows in between. Each row has +exactly as many columns (words) as many props got defined for the presentation. +The first column is always the X coordinate on a two-dimensional plot, the +rest of the columns are Y coordinates for each property (trace). Cells +are in the usual numeric format, without unit. +
